Hi TT, I have a 45G Rohn tower. It is 80 feet tall. I have been trying to figure (without actually trying a piece of steel) what is the longest you can have a piece of 2 inch diameter steel mast inse
Hi TT, Thanks to all the great responses. It may end up being one of those, 'wish I had done that first' kind of thing. The tower is up and has two antennas on the top. One of them is an Optibeam OB-
Well, here is my view: I wanted my new installation to cover 7 bands with beam antennas. I opted for the OptiBeam OB17-4 with the Force12 WARC-7 12 feet above the Optibeam. Seven bands covered with n
Hi, I was told NOT to guy that tower as it would put undue stress on the tower as it is designed to not be guyed - but I can't remember who told me that - I *think* it was someone at US Towers - but
Hi all on TT, I had an unpleasant visit from sparky this past weekend. My 80 foot tower took a hit. The Internet wireless fried. My two antennas seem to be fine. However, my Rotator seems hit. Have a
Thanks for the replies. If the reed relay is welded as many suspect would the reading on the reed line still be according to specs? It is now but about 5.1 ohms? Thanks, Gary, N5PHT The reed relay in
Hello fellow TT, This is Gary, N5PHT. I have a large 10-40 meter beam and I believe my best option is to sell it and I would appreciate any advice on the appropriate asking price. Also, if you are se
I can't help but say: My 80 foot tower and 32 sq. feet of antennas (about 700 feet of aluminum I believe - 24 elements for H.F. total) is in my front yard!! The beauty of it glistening in the moon li
Greetings TT hams, My advisor is on his way to Dayton so I thought I would ask the Tower Talk pros to field this questions. I have the ProSisTel 61D rotator and hope to install it on Saturday. Two qu
Greetings, I imagine I have missed the obvious but my question is how do you measure ground resistance? Does it take a special meter (I suspect it does). I am writing this in reference to ground rods
TT and John, Thanks John - that is very interesting. I have 9 (nine) 8 foot ground rods around the base of the tower. I do NOT have them connected with a large outer circle but may do that. I do have
I am speaking about this in terms of lightning protection. Gary, N5PHT This is one of these questions that comes up periodically for which there is no simple answer. First, what do you mean by "groun
Here is the info I sent to Roger (with a drawing - but I don't think I can include attachments to TT?) Gary, N5PHT I have two LMR-400 lines coming into the shack from the tower. I also have 2 control

Hi Bill and others, OK - I will put in my .02 worth and please remember it is my experience only. I went through three M2 rotators in a year. Now, one of not their fault (lightening hit) but the othe
Let me throw in a few comments and a question or two. I have the Alpha Delta DX-A. It is essentially a sloper with both sides active antennas. One side is for 80 meters and the other side is for 40 a
My experiences only: When I was using a Cushcraft A4S at 45 feet I had a little TVI trouble in my own house (no close neighbors). It showed up on some frequencies and was noticeable but not a real nu
Greetings, Just wanted to share my experience - sorry if it is slightly off topic but wanted to let the group know because I know many of you are dx'ers. I wrote to a Russian ham on email with the qu
I did this BUT is was 80 feet of RG45 - don't know - sounds risky to me. The 80 feet of 45G was fine but I would not want to raise 200 feet not to mention the enormous size of the crane. Gary, N5PHT
Greetings, Well, I am thinking of putting up a temporary (due to my situation) better antenna for 80 meters. I hope to do this for the end of November CW contest. I am trying to finish up some zones
