Franklin Antenna

S

secondchoice

I have read that Franklin antennas can work without the traditional grounding system. Would the commission ever show some flexibility and allow "non standard" antennas for class C & D and as a permanent licensed sites. The commission would still get fees, communities would still have service. There would be less environmental impact from digging for the radials.

There was a licensed station, the old WKDA in Nashville that somehow was the steel in a building in downtown Nashville. An insulated wire between trees, poles, buildings, towers, or on a flat roof has been accepted for STAs. If these systems give decent coverage why not make them permanent?

There have been plenty of rooftop AMs that used a counterpoise system on the roof. Essentially, that is a set of radials up in the air over the roof, often with additional grounding through the building structure.

A number of recent modifications have allowed such a system. KTNQ in LA, about 26 years ago, allowed warehouses to be built on the large plot of land with 5 towers on it. ground system went across the roofs of the buildings and was suspended between each of them in a copper wire mesh system. There was no significant change in coverage.

My opinion-

Through a rulemaking proceeding the Commission might consider it, provided it can be done in a way that prevents creation of new interference, provides required local community coverage, is administratively efficient for the Commission and achievable by broadcasters.

Most horizontal wire antennas would be suitable for daytime use only.

Are long wire antennas omnidirectional? One would think there would be more energy dispersed on the sides of the horizontal wire. Is there any kind of polarization issues with AM receiver antennas?
