I presently am in a restricted sub-division where a man's castle is not the rule. I get permission to plant shrubs. My antenna is the rain gutters. I have 2 stories and I have the gutters in front co
Would not recommend high power into the rain gutter. I used rain gutter at an apartment many years ago also. High power will put HIGH voltages on the gutter which will tend to ignite the building. Fi
500 watts to a non antenna, (the gutters) is not going to fix the basic problem. It could cause arcing and even a fire hazard at some of the gutter joints, that might heat up. You need a designed ant
Live in a CCNR paradise too with no external antennas allowed. When we had this house built 15 years ago, I installed a 40m loop in the attic. It is 40'x20' fed with ladder line down thru the wall an
<< Would there be a problem if I ran 500 Watts into the antenna? >> I'd be concerned about fire, and near-field RF radiation. (Remember, the antenna is surrounding you and your family.) The things we
Before doing this you should also perform an RF-exposure analysis. With significant power running into an antenna that is close to you, there is a chance that your operation will exceed FCC maximum p

I know a fellow who ran a 3-1000Z into a rain gutter in an apartment complex. He had a fairly decent signal on 40 and 75 meters. He didn't have any arcing problems but severely interfered with the ma
Speaking of gutter ant. reminds me: One time in the late forties I had open wire feeders coming from basement up over the gutters to an 8 JK ant. I had put and old rubber tire inner tube between feed
Google "RF Exposure calculator" and you will get the University of TX Amateur Radio Club's on line easy fill in the blank calculator for any RF exposure. Plugging in typical values for 500 watts, and
I wonder if I could use the RF exposure calculator to sue the US Navy for making me work on the flight deck of aircraft carriers that were running some 2 megawatts RF power with their search radar? T
Not sure if RF Exposure limits are retroactive. They were not adopted by FCC until fairly recent years. And Government usually reserves the right to give you permission to sue it. -Stuart K5KVH _____
Yes, that's mucho RF! Any avionics equipment that my company builds for a navy appplication has to be tested in a 200 V/m field. These tests are done with the equipment (and us) in separate shielded
