Hi John I used an A-3 for quite a while and i liked it very much. I bought it for a "compromise" antenna, due to not having a lot of space, and was pleasantly surprised how well it worked. When 10 an
HI Rich I used a loop stretched around the perimeter of the roof for quite a while. Worked good on 160 and 80. Just stapled some wire to the eaves and fed it with coax and a small home-brew tuner. 73
Hi Pete. An antenna over a metal roof works very well, but you need to bond the pieces of roofing together. A lot of roofs are put on with nails that have little rubber washers to prevent leakage. Wh
When my antennas blew down in our last storm, I just stuck the 10 meter antenna on top of the 20 meter to see what would happen. How about that, it worked. No modeling, no guess work, no scratching m
I may be wrong, but I don't think it makes any difference which way the antenna is oriented if it's only 70 feet off the ground. Most of the RF is shooting straight up in the air anyway. That height
Hi All In looking over previous posts, there seems to be an awful lot of credence to computer modeling of antennas. I've seen things like "A three element beam with lengths of (n) and spacing of (n)
One thing I've done that works good it to use a pair of vice grips and a screwdriver. Put the tip of the screwdriver on top of the end of the element with the handle pointing back towards the boom. C
Yep, they made tri-banders and also tri-band quads. I had one of those and it worked great. Worded all sorts of DX with it. Course, now everyone would say it won't work because it had aluminum spread
The first beam I ever bought was a TB-500. I was about 17 at the time and there was a order blank in QST for "$5 dollars down, $5 a month." Sent my $5 and was on the air with a beam. Just in time for
The other day I was messing around and I noticed that the MFJ SWR bridge on radio 2 was deflecting when I keyed radio 1. I have a home-brew all band vertical on radio 2 about 30 feet away from my tow
Hi Dana I'm not too familiar with the 4 square, but I have 3 phased verticals on 40 and when I switch them, it's just like rotating a beam. It is switchable in 6 different directions. BC stations to
Hi Gale et al. I have a piece of wire on teh end of my 80 meter dipole that I just wrap around the uninsulated end of the dipole. It doesn't have to be added to both sides of the antenna. Just add th
Hi Gale et al. I have a piece of wire on the end of my 80 meter dipole that I just wrap around the uninsulated end of the dipole. It doesn't have to be added to both sides of the antenna. Just add th
I may be wrong, but I thought the coils need to be at least 8" in diameter to work. Isn't winding RG8 in a 4" circle kinda stressing it a bit? 73 Tom W7WHY List Sponsored by AN Wireless: AN Wireless
Hi Tom, et al. I have my computer monitor setting just above my amplifier, and when I turn the amp on, I can see the 60 cycle vibrations on the screen. Somehow the power transformer is interfering wi
I don't think so because when I move the monitor farther away from the amp, the waves quit even though the power cords are going through the same hole on the back of the desk. Tom W7WHY List Sponsore

Over the years I've seen lots of postings here about not having one antenna too close to the other. I know it's given me fits when trying to orient different antennas for different bands. While readi
A friend of mine once had his radio hooked up to the Christmas tree lights on his Christmas tree so he could play music into the mike and watch the lights blink (real low power of course). He found o
