Dan etal, I haven't been following this thread closely so pardon me if I repeat something. This note is specifically aimed at 160 meters. The 43 foot vertical is probably OK on 160 if you have a good
Dick etal, For those interested in hearing how well the Cushcraft MAV-160V does, listen to PJ5NA on 1818 running only 100 Watts into same. 73, Joe, W1JR ______________________________________________
Mike etal, I am using such an antenna. I significantly modified 4 MFJ-1792's to work on 80 meters. I first used 16 but later upgraded to 32 1/4 WL radials on each antenna and a Comtek combiner. The f
Roger etc. A good rule of thumb for overlapping tubing it to make the overlap at least 3 times the diameter of the tubing. Hence a 2" tube needs a minimum of 6" overlap and a 1" tube is only 3". This
Jim etal, One of the reasons many Ham antenna manufactures use 6063 instead of 6061 is its appearance. 6063 has a nice bright look while 6061 has a dull appearance. To some this makes the antenna mor
Hi Roger, I don't know where you live but up here in God's Country (NH) 50 miles for the Ocean my antennas seem to stay shiny. In fact, earlier this winter I had to fix one of my verticals that had s
I have tested one of the R3 capacitors. It measured 45-200 pFd. 73, Joe, W1JR _______________________________________________ _______________________________________________ TowerTalk mailing list To
Hi Roger, Just pouring over unread messages. Got behind. Chip Cohen owns Fractal Systems (near Boston) and they are not in the ham market. They do commercial designs (mostly custom) like cell phones
Don, There is a minor resonance just above 17 meters. As many have found, the VSWR isn't that bad at 18.1 MHz and the antenna acts like a dipole with a very slight F/B. It works well there. 73, Joe,
Hi Scott, I've done a little on that subject. Anything you need in particular? 73, Joe, W1JR _______________________________________________ _______________________________________________ TowerTalk
