Typically, putting in radials raises the SWR, but you add them in anyway because they make the antenna more efficient, allowing you to radiate more signal instead of heating the ground with it. You t

My guess is that your transmitter should be the least of your concerns. I'd be much more worried about your receiver. A good voltage drain will not only protect your equipment, but also reduce the no

5. Topband: Question about antenna bandwidth (score: 1)
Author: Rob Stampfli <rob@cboh.org>

If I were to extend my 1/4-wave inverted-L to a 3/8-wave L, and tune out the inductance with a fixed capacitor at the base, what would this do to the broadbandedness of the antenna? Inquiring minds..

Thanks, gentlemen (Eddy, K8GG, ZR, Roy, Herb, et. al.), for all the feedback on this. So, it seems it's pretty much what I expected -- if you tune an antenna for better results on one frequency, you

Thanks, George. Actually, my intent isn't to perfect a DX antenna, but rather, to get the piece of wire with the current maxima up in the air. As it is, with the current node on the ground, I suspect

I use something called "Solder-It Butane Micro Torch", model MJ-300. I think it came from Lowes and cost around $20. Rob / KD8WK _______________________________________________ UR RST IS ... ... ..9

Author: Rob Stampfli <rob@cboh.org>

The signal is at times peaking at S9+20 here in central Ohio, with a bandwidth from approximately 1900 to 1930. It appears to be rapidly sweeping up the band at a rate of about four sweeps per second
