Yes, I meant they are in an equilateral triangle. Had a brain fart. Lots of postings on this subject, but nobody has yet answered my original question. I'll post it again. I have 2 stubs, separtated
For interstation interference reduction Tuned to the CW part of 40 I have a line from my rig to a stub, 1/4 line to the next stub, then to the antenna Tom W7WHY ______________________________________
Hi Gary Yep, they are on the line between the transmitter and the "T" fitting to the network. I tried them out last night (with 2 of the 3 verticals) and didn't seem to make much difference in the SW
Hi Rex Well, it all depends on the thickness of the elements. 73 Tom W7WHY _______________________________________________ _______________________________________________ TowerTalk mailing list Tower

Some of the products on the market, like Ospho, really work good on rust, but the problem is that as long as there is rust, it will keep working. It can eat all the way through some pretty hefty meta
Hi All I have 3 phased verticals for 40 and an inverted "L" for 160. At the base of each of these, I have a pretty extensive radial system. I run a wire from the radials at the base of each antenna t
Yeah, either that or get them into the hobby :-) 73 Tom W7WHY _______________________________________________ _______________________________________________ TowerTalk mailing list TowerTalk@contesti
Same here in Coos Bay, OR. If you think the farm stuff smells bad, how about shrimp shells and crab shells :-) Here the farmers take the residue from the fish plants and put that on their fields. Sm
All well and good if you can get to the tower. If I used a crane to put the antennas on my tower, I would have to remove the house to get it back there Tom W7WHY _____________________________________
Hi Dino Click on this link http://www.google.com/search?hl=en&lr=&q=%22gamma+match%22 Found a bunch of stuff on google on gamma matching. One looks pretty good using 2 pieces of aluminum tubing and
If you want to make it really easy, and work good, change it to 2 elements, space the elements about 1/4 wave (with split driven element that is) and it's 50 ohms. Feed it with coax and go. Make a gr
I don't have a clue what this means, or what it has to do with antennas. Guess I'm dumb or something. 73 Tom W7WHY _______________________________________________ ___________________________________
Hi Lee I think if you are not using a balun, the length of coax will make a big difference in the SWR. You might try adding a chunk of coax and see if it changes the antenna. I have a couple of ante
Hi All Some years back, there was an article, I believe in QST, about some vertical antennas wound on 2 pieces of pvc pipe. They were for 40, 30 and 20. The bottom section was wound for 30/40 and you
Huh, wonder where you got that? Go to http://se.cessna.com/ and they have a complete line of piston powered airplanes. This is a quote about the Skylane: "The Skylane is acknowledged as the best all

Hi all Going to put up a 40/20 (probably use the 40 on 15) multiband vertical for field day. Do they work better with 1/4 radials for each band, or would 1/4 wave radials for 40 work on 20 OK? 73 Tom
