Antennas for the R-390A
ANTENNAS FOR THE R-390A Feeding the Antenna Input by Chuck Rippel June 1999 Connecting an Antenna to the Input of the R390A is a subject that comes up often. The R390A has two, rear mounted antenna inputs. One is marked ``BALANCED" and the other, labled ``UNBALANCED." Most new R390A users will choose to feed the antenna through the ``UNBALANCED" input. Unfortunately, the receiver suffers some loss of sensitivity. The correct choice is to fed the receiver using the ``BALANCED" input. Unfortunately, the connectors to properly accomodate this a rare and when they are found, expensive. However, there is an easy around this dilemma. The antenna is fed into the right side of the ``BALANCED" input with with center conductor of RG8X or RG-58/U. As shown in the picture to the right, the left side of the antenna input is grounded VIA the red wire which is inserted into the left hand pin jack and the opposite end grounded VIA the one of the 4 antenna relay assy mounting screws, located just below and to the left of the connector. In the case of RG8X, some of the center conductor strands, usually about 3, must be removed in order for the center conductor to fit into the small antenna input pin- jack. The co-ax is then made up in an appropriate length and terminated in a PL-259 connector for easy connection to your antenna system. After installation, best peformance is obtained when the receiver is also aligned using this input. The enterprising R390A owner who is also handy with sheet metal fabrication can add an SO-239 connector to the antenna input of their receiver. -

BOARD OF COUNTY COMMISSIONERS PLANNING DEPARTMENT STAFF REPORT BOCC Hearing Date: October 24, 2019 To: Park County Board of County Commissioners Date: October 17, 2019 Prepared by: Jennifer Gannon, Planning Technician Subject: Special Use Permit Request: Special Use Permit for a New Telecommunication Facility Application Summary: Applicant: New Cingular Wireless (AT&T Wireless) Owner: United States Forest Service Location: An area within Section 35, Township 11, Range 73 (i.e. the summit of Badger Mountain), addressed as 4150 Forest Service Road 228. Zone District: Conservation/Recreation. A zoning map is included as Attachment 1. Surrounding Zoning: Conservation/Recreation in all directions. Existing Use: Antenna farm. Proposed Use: Existing, failed AT&T tower to be replaced. Background: AT&T has had a lease with the Forest Service and an 81-ft. lattice tower on Badger Mountain since 1994. The tower recently broke and is now less than 40 ft. tall, with one microwave dish antenna still attached and working. AT&T is requesting a Special Use Permit to construct a new 80-ft. lattice tower which will include upgraded equipment for commercial communication, as well as for the FirstNet program, which will operate a nationwide public safety broadband network. The new tower will be built approximately 20 feet from the old one. Once the new tower has been installed the old, failed tower will be removed. An aerial vicinity map, aerial view of the site, and site plan are included as Attachments 2, 3 and 4. Land Use Regulations: The applicant has met all applicable requirements of Article V Division 9 of the Land Use Regulations, the Conservation-Recreation zone district, and the Park County Land Use Regulations. -
