A detailed report and analysis has been prepared for VideoTele.com and their client Consolidated Communications. Technical input for this report was provided by: Wade Antenna and FCC databases. The RF path loss formulas follow Longley Rice RF propagation models. Three second topographic elevation data was used for all points between broadcasters and the receive location.

A large amount of reference information has been assembled within this report. Please retain within your system records for future reference. This document will be very useful if any level deterioration may occur with any received signal. A report containing the actual measured levels after initial construction should also be retained for comparative purposes.

Drawings containing the grade A and B signal contours have been included. These will serve several purposes. They represent a quick look at your receive site position; with respect to the broadcasters. They will also serve as a reference for various levels of FCC compliance requirements. The following is a brief description of these established levels.

The FCC established three signal contour grades for broadcasters and receivers to reference. An FCC defined “City Grade Service Contour” is a location in which indoor, or low gain outdoor antennas, can be deployed to produce a noise free picture. A “Grade A Service Contour” is generally defined as a location distance where a standard television antenna placed at 30Ft. above the ground can produce a clear noise free picture. The “Grade B signal Contour” represents a radius where a 30Ft antenna can be used to produce a reasonably good picture that will contain some noise. It is important to note that higher and larger antennas can extend these receive ranges; additional noise can be expected. It is the ratio of signal level to the ambient noise levels that change the perceived viewing quality.

For reference purposes the table below defines the FCC signal contours

Channels Grade B Service Grade A Service City Grade Service Contour Contour Contour Channels 2-6 47 dbu 68 dbu 74 dbu Channels 7-13 56 dbu 71 dbu 77 dbu Channels 14-69 64 dbu 74 dbu 80 dbu

The above text and information charts are used to describe typical analog television broadcast field strength as presently used by U.S. broadcasters. At present an entirely new broadcast technology is being phased into operation in the United States. This is a transition to digital broadcasting. This new service is generally referred to as DTV (Digital Television). The transmission system is 8VSB.

The FCC has provided a phased step migration toward, what will become an all digital over the air broadcast system. Generally speaking each existing analog television station was allowed to occupy another channel for DTV transmission during this process. Rules governing interference with the existing operations were relaxed in order to facilitate this migration process.

Transmission power levels and receive signal strength are different for DTV signals. It was the FCC’s goal to grant broadcasters a power level that was expected to closely provide the same coverage radius as their existing analog footprint.

An analog television signal will slowly degrade with distance and signal level. This characteristic is not true with a digital broadcast. One very positive attribute of a DTV signal is the consistently high picture quality that is achieved. However, this same positive characteristic also creates a signal cliff effect. A digital signal will continue to render a very high quality signal until the receiver can no longer lock to the signal. This is a very sharp point. A small change in received signal level, or drop in carrier to noise ratio will unlock the received picture. The picture will begin to tile and then be lost completely. For these reasons the former signal grade designators do not provide proper information for a DTV signal.

The FCC has adopted the long used grade “A” and grade “B” signal contours. The categories are DTV Noise-Limited Service area and Minimum Field Strength over the Community of License. Generally the classifications of antenna height and type drop away. The reception limiting factors become signal level and carrier to noise ratio. The chart below will help explain the new signal level classifications that are used to calculated approximate signal coverage contours. The timing phase in process for increased signal level was designed to lessen capital cost issues for broadcasters. This field strength phase in is an important factor to remember. It is possible that even a relatively local broadcaster may not be receivable until full operating power has been reached.

These tables have been established as a relative guide. The actual results will vary greatly. This is especially important at receive locations where greater than average amounts of noise may be present. To an analog signal noise may have just been the source of impulse picture problems. In a DTV environment the same noise sources may prevent picture lock completely. Time of day and weather conditions can have a great impact on final results. A marginal location may have perfect received picture quality until certain times of the day or weather pattern changes. We share this information so that the reader may can some understanding of the process and new key parameters.

Channels DTV Noise-Limited Minimum Field Service Strength over Community of License After Dec 31, 2004 (For all Commercial TV) or after Dec. 31, 2005 (For Noncommercial Educational TV) Channels 2-6 28 dbu 35 dbu Channels 7-13 36 dbu 43 dbu Channels 14-69 41 dbu 48 dbu

All of the desired analog and their corresponding DTV signals have been evaluated. Each signal that may present co-channel interference has also been examined. It should be noted that the broadcast universe is not static, but changes. The information and recommendations contained within is a snapshot of the environment at this time.

iii Summary of Off-Air Study

Our on-site off-air signal measurement study consisted of four sites: Existing sites at A , B, C, and D . Each site will be summarized separately in their own report. This report shall focus on the D site.

A Site

On-site field measurement study

This site is an existing hut location without an existing tower. The site is on local hill, in a residential environment and is seemingly unencumbered by terrain features. Local building and trees would raise minimum height requirements. The survey was conducted on a sunny warm mid-afternoon. Several channels were tested and the following are observations made during the site visit:

1. In general this site was very hostile to analog reception. All analog channels exhibited some form of: Heavy ghosting, electrical interference, or such poor signal levels as to be unwatchable. We were unable to receive any of the X Low Power stations, as well as the Y stations.

2. The digital version of KXXX did not seem to be on at all.

3. We tested the digital channels with a special 8VSB meter that measures various error ratios in detail. All the digital channels at this site had (with the exception of KXXX) poor carrier levels and error ratio measurements.

It was determined on site that this location would be unsuitable for off-air reception. No further study of this site is discussed in this report.

D Site

On-site field measurement study This site is an existing hut location without an existing tower. The site is on flat level ground, in a rural environment and is seemingly unencumbered by terrain features. The survey was conducted on a sunny warm mid-morning. Several channels were tested and the following are observations made during the site visit:

1. In general this site was very hostile to analog reception and digital reception. Heavy electrical noise was prevalent throughout the analog channels and noise could be seen prominently throughout the RF spectrum.

2. The electrical problems at this site were so thorough, that further testing was discontinued.

It was determined on site that this location would be unsuitable for off-air reception. No further study of this site is discussed in this report.

B Site

On-site field measurement study This site is an existing hut location without an existing tower. The site is on flat level ground, in a suburban environment and is seemingly unencumbered by terrain features. The survey was conducted on a sunny warm mid-morning. Several channels were tested and the following are observations made during the site visit:

1. This site represented a vast improvement over the other two sites. Signal levels and picture quality on all major desired stations were acceptable.

2. The electrical problems that were observed at the B site (which was done the night before) were not seen at this site.

3. All levels were slightly lower than that at the B site.

4. While KFXX-LP 30 was acceptable, the other local LP stations- KXXX 5, and KXXX 13 all exhibited either very poor signal level noise or heavy electrical impulses. (KXXX, it was noted had the same issues on the local incumbent’s version as well.)

Off-air detailed paper study

The list of channels to further study was brought down to five. These five channels plus their respective potential co-channel interference source stations were all analyzed in detail at our office. The five channels are: . From the data on the following pages we have determined several things:

v 1. The B site was originally favored and thus emphasis was placed on studying this location. Upon further study and coupled with the fact that a local heliport prohibited any sizable tower construction, it was determined that this site would be dropped in favor of the C warehouse site. The C warehouse site was not actually tested on-site, however, it is reasonably close in proximity to the actual testing site as to be practically the same. This site is where the balance of this report shall focus upon.

2. Both the analog and digital channel calculated receive levels correlate to the on- site measured levels. This shows that the real-world environment is not any more hostile to the off air carriers, than is indicated by the calculated figures.

3. Referencing the Broadcast Signal Contour Maps on pages 2-3; This tower site is not in the best location to meet all coverage areas. For the most part it is within Grade B, but not in equivalent This information supports the pictures found in the field and also reinforces the assertion that this site may and probably will be prone to periodic signal degradations. These signal level changes may affect picture quality on channel 22 and especially 31.

4. KXXX should be noted, is a compromise at this site. At the time of testing the signal for this channel could not be found, which may indicate that they were not on at the time, or it could mean that the level was too low for our instrumentation to measure. In either case the calculated demodulator input level is fairly low and the resulting picture may be compromised is atmospheric conditions degrade the signal level further.

5. Potential co-channel interference sources were analyzed for all desired analog stations. While several co-channel-to-desired channel ratios are close, based on our analysis co-channel interference from other broadcasters should not be a factor for all the desired stations.

Summary

During our on-site visit, we tested four separate locations to see which has the best off-air reception potential for the five channels in question. The C warehouse site was eventually chosen based on available tower erection space, proximity to the CO and limiting factors at D. While the D site is not an ideal location for off-air pickup in this market, it represents a reasonably sufficient reception location, considering the challenges of this market.

The final conclusions and tower/antenna diagrams assume a new 180 foot tower is to be erected.
