I may have missed something here. Perhaps someone could explain it to me. I have been a ham well over 50 years and have put up and helped put up quite a few towers. I have never seen the need for tem
I use greater spacing than has been described in this thread. (30' for 24' boom 5el 6m antennas and 50' for 7el 48' boom 10m antennas) The forward gain is higher. Why should I worry about the side lo
I do not use an H frame, I was just talking about the spacing. If I had an H frame, I would use closer spacing to cut down on the construction problems. I should have clarified this. Chuck W5PR _____
If Towerair on the FCC website shows my tower coordinates ok to 199 feet, will I probably be ok with the FCC? We have a couple of short, grass runway airports in the vicintity. I made a FAA applicati
I think 40 and 15 on the same tower is the problem. Chuck W5PR _______________________________________________ _______________________________________________ TowerTalk mailing list TowerTalk@contest
This idea just occurred to me: One way to do this might be to put a stacked antenna matchbox up there that would select "Upper," "Lower" or "Both" antennas and one could drive both antennas in phase
It has to be a JA card. I am not superstitious, but I did this in all my tower holes before the pour. (Just to be sure!) Chuck W5PR _______________________________________________ ___________________

Now you are making fun of a serious matter. You wouldn't want anyone to spend 600 bucks to drop a truck load of concrete in a hole and then find out it was useless because they forgot a simple thing
I feel sorry for you guys that have to put up with those nasty old Redwood trees! :-) What kind of rotor is it? Some types are more susceptible to binding. Have you tried momentarily reversing direct
If you had a Sterba curtain or a rhombic you could just plug the coax into 110v and melt it off! Chuck W5PR _______________________________________________ ___________________________________________
W9IIX no longer makes mast steps. I used to have a listing of someone who makes aluminum mast steps, but I can't find it. I need about 4 steps for a 2' mast. Does not have to be aluminum. Any ideas o
If you have moisture in the coax, it can act like this. There will be a high resistance path to ground which will heat up on transmit and reduce in resistance, causing the SWR to rise. Test the coax
I like gamma matched beams because you don't need a balun and there is no DC short to ground at the antenna. You can check for shorts and high resistance paths to ground from the shack. Chuck W5PR __
Is the Yaesu G-1000 rotor bolt pattern the same as a T2X bolt pattern? Chuck W5PR _______________________________________________ _______________________________________________ TowerTalk mailing lis
Is the Yaesu G-1000 rotor bolt pattern the same as a T2X bolt pattern? Actually, my question is "will a Yaesu G-1000 rotor bolt onto a standard Rohn tower shelf without drilling? Chuck W5PR _________
The specs for the standard accessory shelf look to me like it is drilled for both Yaesu and Hygain rotors. Here is the spec sheet: http://www.3starinc.com/manuals/ROHN_AS25G.pdf Chuck W5PR __________
I have one of each. Will the DXA manual serve for the SDX? Are there any practical differences? Specs seem to be the same. Chuck W5PR _______________________________________________ _________________
I think they will probably affect each other. I would check the SWR of both on 10 meters and then mount the beam below the tri-bander and see what the difference is. If there is a major change in SWR
