I see at least one Rohn 45 seller's web site that calls the tabs on the 45AG4 top plate guy tabs. However I don't see any reference to that in the Rohn documentation. Except for dimensions Rohn doesn
Yes I believe that they can be used to secure the guys. I chose not to do this since it is already cluttered up there and having the guys attached to the top plate makes working on the antennas more

The typical guy tabs form a yoke "around" the tower so the tension is not on any one leg as opposed to tying them off on a tower leg as is often seen. The tower flat top plate appears to distribute t
I used the top plate holes to guy the P40A Rohn 55G tower and it worked out well. The top plate hole was too small for my guy cable thimble so a shackle was needed. I see at least one Rohn 45 seller'
I agree. Having the guys on the top plate is a real pain. My first Rohn 25 was like that. It was very frustrating installing a beam with a tram system. Install a guy ring 4-5 feet down the tower. 73
Yes, I installed my guys about 5 feet down from the top of my Rohn 45 tower and the rotator is about 8 feet down from the top of the tower. It seems to work out pretty well. I took the advice of othe
It's not a problem at all if you just drop two of the top guys when installing the antenna. John KK9A I agree. Having the guys on the top plate is a real pain. My first Rohn 25 was like that. It was
I rarely use a tram line. If I did I would not set it up 6 feet above the tower and I am sure that the one remaining guy that I suggested would adequately offset the tram line force. John KK9A That w
Thanks for the input. FWIW I was trying to raise the top set of guys to get a bit more clearance for a yagi that will be on a ring down the tower. Also my mast is very tall and it seemed a good idea

The good of guying to the top plate as I see it: My guys are Phillystran with open spelter sockets. So I just have to take a cotter key out of the pin in the end of the socket and I can instantly att
That would be my last choice. Especially when you have a tram line attached 6 feet above the top of the tower stretching 100+ feet out. 73 Jim W7RY It's not a problem at all if you just drop two of t
I don't want to up there with a tram line dropping guys from the tower. Mark N1UK It's not a problem at all if you just drop two of the top guys when installing the antenna. John KK9A I agree. Having
Mark you have an 86' Rohn 45G tower with two sets of guy wires, the bottom one is at 39 feet. In this case I would also not feel comfortable being up there with 47 feet of unguyed tower, even without
You mention 600 UF. I've used a fair amount of it and found very poor life with the stuff. Poor resistance to UV and easily abraded if it rubs against something like the tower top in a rotator loop.
BuryFlex from Davis RF. Someone else is selling a cheaper version, but I can't remember who. 73, Mike NF4L _______________________________________________ ____________________________________________

I use a lot of Davis BuryFlex(TM), but I'd not recommend it on 1296. I don't operate "up there" so I don't know what the going choice is, for low loss, "relatively" flexible cable for rotator loops.
Hi All, I use LMR600U for a flex loop on 2m, 70cm and 23cm. On the higher frequency bands the TX power amplifier and RX converters are located at the antenna so only a run of LMR240 is used for the 1
