So true! I remember years ago, I was going to get my first beam. I was a broke teen-ager so those Gotham (remember those) antennas looked pretty good to me. $21.95 for a 3 el. 20. An old timer told m
Hi TT'ians! I want to try my 160 inverted "L" on 80. It's 125 (+-) feet long and I would like to feed it at the base. Does anyone know the values for an L network I could use for this? Thanks Tom W7W
There was an article in one of the magazines on using antenna across the band. I think it used some kind of 75 ohm transformer in the feedline. I've since lost the info. If anyone has it I would also
It depends on how you want to set it up--maximum gain, bandwidth, FB or matching. I built some 10-20 meter 2 el. monobanders and with .25 spacing, the impedance is right at 50 ohms. No matching netwo

Hi David. I found the article here in my library. It was farther back than I thought (man, where does the time go). It's in the August 1986 issue. The name of the article is "A Short Vertical Antenna
Hi Ken If there are any farmers around your area, chances are you can get some irrigation tubing for a good price. I found some damaged sections just for the cost of hauling them away. 73 Tom W7WHY -
HI Dick I have been using 3/8 poly rope for antenna supports here. The ones holding up the 80 meter vertical and 160 meter inverted "L" have been up for about 8 years now and no problems. I also have
Hi Steve Maybe you could share some of the ideas you got. I have the same problem as you--cubes plugged in everywhere. I'd like a nice neat installation. 73 Tom W7WHY -- FAQ on WWW: http://www.contes
Hi All I did that with my 160 meter inverted "L". I used some heavy duty TV twinlead for the linear stub. Shorted one end and hooked the other to the coax and the antenna. Once I found the right leng
Hi Steve, et al. I saw a program on The Learning Channel the other night about lightning. One place in the show showed the lightning protection for the Space Shuttle while sitting on its launch pad.
