Howard, Good idea on the checklist, particularly for safety gear. It's comforting to know I am not the only one that experiences the "oh **, I forgot the...." when I get to the top of the tower. I wa
Jim, I have a US Tower HDX-589 and also use their standoffs. I like the idea of yours to use a 90 degree PVC sweep elbow on the top standoff. May do this myself. Do you have a picture showing this to
Dave, Great idea ! I forgot about ductseal. Bob K6UJ _______________________________________________ _______________________________________________ TowerTalk mailing list TowerTalk@contesting.com ht
Roger, I have some LMR 600 ultra flex that I will need to do a turning loop arrangemet with. I am wondering if it is possible to do a 3 or 4 turn coil that is in a spiral configuration around the mas
I use one between my K3 and 160 meter flag antenna for receive. No attenuation at all in received signal and no worries now about too much RF getting back into the K3 from the receive ant line. I sec
Mat, Sounds like a very good ground system. I have a question on one thing. As part of your grounding system you mention connecting to the rebar. I assume this is the rebar cage that will be cast in
Dave, Wow, did I hit a nerve ? Didn't mean to stir up deep rooted feelings on this subject. Lets take one thing at a time. Our local building code does not specify connecting the tower to the rebar c
I have an LP-100 also. Very hapy with it. As Steve says it will give you impedance data also. I used my old trusty Bird wattmeter before, but I had to change slugs for low range and for higher ranges
Felipe, I have a Cushcraft D40 4 feet above a Force12 C3S tribander. The D40 is aligned parallel with the boom of the C3S. I have zero interaction between the two antennas. I called Force12 and asked
Heres a source for drift pins that structural steel fitters use for reference. http://www.ajaxtools.com/prodlist.php?dept_id=11 73, Bob K6UJ _______________________________________________ __________
My 40 meter Cuscraft D40 is only 4 feet above the Force 12 C3S tribander. I could have explained it better, the D40 is 90 degrees off of the C3S, the D40 is in line with the boom of the C3S. I would
Steve, You are correct, I had it backwards. The KLM antennas have the elements insulated from the boom, and Force 12 parasitic elements are connected to the boom. Thanks for pointing it out. Yeah, in
You guys have me interested also. I have a small lot only 70 feet by 120 feet. Do you think I would wasting my time with this small of an area for rolling out the ground screen for the low bands ? Bo
Great article on the mesh. Thanks Ian, very much appreciated ! Bob K6UJ _______________________________________________ _______________________________________________ TowerTalk mailing list TowerTal
I have been gathering up materials for rolling out galvanized chicken wire for a ground screen from my vertical as discussed here recently. I'm trying to figure out how to make the electrical connect
Gene, Good ideas ! I see your point about using SS hardware. tnx, Bob K6UJ _______________________________________________ _______________________________________________ TowerTalk mailing list Tower
Sounds like the .03 dia aluminum wire probably wouldn't last very long. I have a bunch of rolls of copper coated mig wire for steel welding that is also .03 inches dia. Others that have tried this st
Al, The CAT5 cable sounds good, thanks for the info. Yes many of us hams are characterized as being cheap. I agree with the QST columnist that chastized QST readership providing the cheap ham stereot
I have a Force 12 C3 and I'm considering buying their 40 meter dipole to mount on the boom of the C3. A couple of questions for someone that has done this to their C3: How does it perform on 40 meter
