Had a similar one and junked it out. Could have been from a BC-610 transmitter. Somewhat less than half of the weight was copper. The primary winding wire was not round, but about 1/4 inch square. (B

Hi Dave, My first thought is an artificial noise floor from some device at your location. How much S meter difference between antenna off and antenna connected ? Do you have battery power for your tr

Reminder: High winds, especially with cold dry blowing snow, can develop dangerous voltages on antennas. A danger to life and equipment. A coil to ground as in a L network, can drain off a lot, but p

It's refreshing to get input from many sources. I always believed that the static was not from a nearby tower as I have three close by. The BOG antenna did not hear the noise, but other antennas did.

Thanks Bob. We need to keep saying this as there are a few that keep saying "shutting down for the season". It often leads others to think the 160 meter band is dead for a season. Mother Earth does h

Without doubt foliage has measurable effects on the antenna when it is close to a voltage point (speaking from experience with loops), so Carl's findings make good sense. Bob VE7BS Detuning of low ba

Another way of looking at it: There is loss in vegetation that goes up as the frequency goes up. At low frequencies, in a seconds time, only a small amount of wavelengths pass through a given bit of
