ZS6BKW Vs G5RV Antenna
ZZS6BS6BKWKW vsvs G5RG5RVV Antenna Patterns/SWR at 40 ft Center height, 27 ft end height ~148 Degree Included Angle Compiled By: Larry James LeBlanc 2010 For the AARA Ham Radio Club Note: All graphs computed using MMANA GAL http://mmhamsoft.amateur-radio.ca/mmana/index.htm ZSZS6BK6BKWW // G5RVG5RV WhaWhatt isis it?it? In the mid-1980s, Brian Austin (ZS6BKW) ran computer analysis to develop an antenna System that, for the maximum number of HF bands possible, would permit a low Standing Wave Ratio (SWR) without antenna tuner to interface with a 50-Ohm coaxial cable as the main feed line. He identified a range of lengths which, when combined with a matching ladder line length, would provide this characteristic. According to an acknowledged expert in computer antenna design and modeling, L. B. Cebik: “Of all the G5RV antenna system cousins, the ZS6BKW antenna system has come closest to achieving the goal that is part of the G5RV mythology: a multi-band HF antenna consisting of a single wire and simple matching system to cover as many of the amateur HF bands as possible.” Both are “good” antennas and will work well in defined situations. This presentation is not designed to “bash” the G5RV, but to possibly convince you or a new ham to enjoy the benefits of lower SWR, lower loss, and greater signal strength by using the ZS6BKW version of a ladder line fed dipole. ZZSS66BBKWKW // GG55RRVV WWhhyy II liklikee itit 1. Has low swr in several ham bands at the matching point at the end of the ladder line resulting in lower losses in the coax cable.

The lower ends of the two lines should be stripped and bent over and soldered together. The resultant active line length must be 13ft. The dis- tance from the centre insulator to the ladder line should be 17.5ft. If you have a lot of wind in your area you might want to tie a 1oz lead fishing sinker to the bottom of each of the phasing lines. Alternately a string can be attached and tied to some secure point below the antenna.

Lantz Program Chairman The conference theme this year is “Systems and Technology in the ’80’s: Expanding Horizons.” It was selected to continue the theme which began with ITC/USA ’80. The technological advances that have occurred over the past decade have, and continue to have, a profound affect on the nature and applications of telemetry systems. It is felt that the papers and tutorials which make up this year’s conference will provide you with some insight into these “Expanding Horizons.” The technical exhibits compliment the technical sessions.

These articles are the hard work of Wayne Sarosi KB4YLY (995 Alabama Street, Titusville, FL 32796) SUBJECT: Circular Polarized Antenna There has been a request for a series on 'CP' antennas. The term 'CP' eluded me at first as I was not familar with the abriviated designator for circular polarization. At work, we just use the entire words. I'm going to begin this ten part series with the basics. After researching CP designs with a few engineers and fellow hams, I found that they knew very little about the subject. I also found I didn't know quite as much as I thought I did about circular polarization. So starting at the begining will help all out. First, let's discuss the circular polarized wave. There seems to be conflicting standards used by the world of physics and the IEEE. I found this to be true in four reference manuals including the ARRL Antenna Handbook. At least it's stated right up front but biased according to which text you read. We will follow the IEEE/ARRL standard in the following series for obvious reasons. There are two types of circular polarization; right and left. All of us agree up to this point. According to the ARRL Antenna Handbook, the following statement: 'Polarization Sense is a critical factor, especially in EME work or if the satellite uses a circular polarized antenna.
