Calling it a law confuses people. I never made that statement. Oops, you're right.. It was "w4jle". But you took his side :-) See, one of the groups this got cross-posted to is an *Amateur Radio Antenna* group. I'm reading and writing it from this group and commenting from that perspective. I normally don't cross post but did the first one by accident and since I've developed such a loyal following I didn't want to lose anybody G. But we were discussing Frank's observation: It's been my experience that an antenna used for receiving will function satisfactorily over a much broader range of conditions (environment, antenna length, etc.) than it will if used for transmitting under those same conditions. Certainly below 30 MHz this is represents a correct observation, verifiable both by calculation and experiment. Why should this reality change with the newsgroup? Tall tree? What's a tall tree? The best I have is some 35 foot tall Saguaro cactii. They're a bitch to climb, although when the coyotes went after the cat, she managed. Let's see, I could tie a string to the cat's tail and find a coyote..... Sounds like you're in "Beverage on the ground" territory. That works too, I'm told (I live next to a swamp, so the tall maples are my friends :-). I've never tried a Beverage on the ground, although I have used a long skinny island as a slot antenna (worked very well from longwave through tropical bands, useless above 10 MHz). -- | John Doty "You can't confuse me, that's my job." | Home: | Work: |
