Bud I don't know if the middle of the boom has room for a TIC. Seems like the DE's will not allow enough room for mountingKLNS

? ? So how is it "acting up"? What symptoms does it have? It's a decent antenna so it might be worth repairing.

? ? If you're considering a new antenna, I'd suggest the K4RIO (I think that's his call) Hex Beam. Almost negligible windload and works great.

Thanks Mike
I am very footprint conscious in this location but I know it is a great
antenna. The KT34a elements ahve a lot of space between them looking OK..
Maybe Navassa would not look worse

Subject: [TowerTalk] Skyhawks on TIC Rings?
Message-ID: <004201d4a82d$82825040$8786f0c0$@gmail.com>
Content-Type: text/plain; charset="us-ascii"
I currently have a 3 stack of KT36XA's on a Rohn 55G tower. They are
mounted on TIC Rings - Model 1122E. I am considering replacing the KT36XA's
with Skyhawks.
Does anyone have experience mounting Skyhawks on my configuration - Rohn 55G
/ Model 1122E TIC rings? If so, was there anything tricky about the
installation? I am particularly worried about the potential need to mount
the antennas off of their balance point.
Any other thoughts or advice?
I know that K3WW is using a similar configuration and I have already gotten
an input from Chas.

Hi Bud,
There is a fairly simple way to address and change the balance point of a large antenna so that it is not an issue.
Here is the brief version ? if you are interested we can talk further.
On my 15 and 20 meter yagis, I take the cap off the end of the boom then using lead sheeting which can be purchased at Home Depot or similar store, I cut off a piece and roll it like a sandwich wrap and place it at the end of the boom that needs additional weight to balance. I put a small mast in the boom to mast clamp and have it stick out of the bottom of the clamp by about 1? ? which I balance on a flat tree stump (or table top) and go back to the boom to mast clamp and make sure that it can balance, if not I repeat the process with adding or subtracting more or less lead sheeting at the end of the boom. When it balances just right at the clamp, I drill through the bottom and top of the boom in the middle of the lead sheet and put a long eyebolt through all of it and then bolt and seal it on both ends above and below the boom.
You now have a well balanced antenna that will remain so forever.
My 5L yagis are very easy to work on even in windy cndx because they are balanced at the boom to mast clamp. This makes them easier to control, safer to work on and reduces the stresses on the rotator and tower. It also prolongs the life of the boom to mast clamps on the antenna since there is less ?play? in the ice and wind.

Good stuff.
You can do similar to balance the antenna aerodynamically so wind gusts
don't try to rotate the antenna.
