Hi Dan Back in the late 60's, early 70's Gotham made a 3 element 20 meter beam for around $25. Gamma or "T" match--take your pick. Worked great! Probably lots of them still around. That's when Telrex
Hi All There used to be an old carpenter axiom, "Measure twice and cut once." I've found out over the years that works pretty well. 73 Tom W7WHY -- FAQ on WWW: http://www.contesting.com/FAQ/towertalk
Hi All In light of the horrible QRM in last weekends 160 test I got to thinking about a beverage again. I had one here before but didn't use any un-un's or anything like that to feed it. I just used
Thanks for all the replies. The consensus is to go with the transformer--mainly for isolating the feedline from the antenna. There sure is a wealth of information on this reflector!! 73 Tom W7WHY --
And lets not forget the grand old man of DX'ing, W6AM and his rhombic farm. Rotary yagi's are great, but don't have the mystique of a good rhombic farm :-) 73 Tom W7WHY -- FAQ on WWW: http://www.cont
Hi Dan I live on the N.E. slope of a hill that is about 450 feet ASL. The hill slopes off at an angle of about 30 degrees towards Europe. My experiences with a 3 element vertical array is that it kic
A wide swr like that is a sure indication of loss!! You could forget the radials. Just drive a piece of pipe in the ground, connect the ground shield to it, and have a great SWR. That is one reason

HI Herve. One of the first things to ask the person who gives you a bad report is if they have their noise blanker on. Loud signals will sound very distorted if their noise blanker is on. Is the new
Hi All I'm now using a inverted "L" for 160 and it seems to work pretty well. I have lots of radials under it which seems to make it play OK. I was wondering if it would be better to elevate the end
Hi Pete. I think it must have something besides a petroleum distillate in it because it is widely used on fish bait and crab bait here in Oregon. Salmon fisherman spray it directly on the bait whethe
I just wonder, does that still count as a "tri-bander" in class determination for contests or is it 3 monobanders fed that way? 73 Tom W7WHY -- FAQ on WWW: http://www.contesting.com/towertalkfaq.html

Hi Lee I remember them as I had one for 80. Nothing magical about them. Just a huge piece of coil stock in encased in a plastic tube stuck in a antenna mast. They were big and bulky.. I liked the Hus
Hi Jim If there are any farmers in your area, sometimes they have some irrigation tubing that has gotten bent of smashed. That makes good antenna material and you can get it pretty cheap. Sometimes j
You have to also remember that using a 160 meter dipole that is close to the ground, 40-50 feet, the impedance can be very low, sometimes in the order of 4-5 ohms. That is almost a dead short across
Hi Gang I've been wondering about some things. Say 2 3 element monobanders are stacked, the gain goes up 3 db (at least that's what I think). If there is 100 watts going to the antennas, when it reac
