Hi Fred. I am curious as to any negative impacts on bringing the gamma rod in and out. I am shunt feeding my tower. I miss having the side mounted lower beams. Wasn't sure the shunt feed would even w
Does anyone have a Hygain BN4000B laying around? If so pse get back to me. MFJ is out of stock. Want to take one dwn with me to V2 for the TH7. The reason I want to use a BN4000B is that they seem to
Has anyone tried shorting the reflector to the boom on the XM240 to see if it behaves better with tribanders like the 40-2CD? Do the dimensions have to be changed on the reflector? Tony N2TK Well I m
What is the general consensus for where the 4 square should be resonant? If you want to cover phone and cw, is it best to; - set spacing and length of 70 ohm lines to 3.650. Then resonate verticals a
I use an FJ-1118 outlet strip. I picked up several in-line fuse holders with pigtails at Dayton. I use one of the pigtails to replace a cube 12v supply. This way I am fused properly for each device.
I am looking for stainless steel square nuts for the Hygain clamps. 1/4-20 and #10-24. Also looking for ss hex head bolts - #10-24 x 2". A dozen of each would be sufficient. Checked local supply plac
I have an elevated feed 80m 4 square. The "vertical" wires go from the feedpoint to the top of an 80' tower. The wires are about 55 degrees above horizontal. My question for those that have and know
I did not have any trouble drilling 4130 mast either Tony N2TK You guys have me worried mentioning how hard it is to drill 4130. Just put a 20 foot stick of 4130 1/4inch wall in my tower. I drilled 2
The Tailtwister manual says the cap is across pins 4 and 8. It's value is 120-140mfd at 50VAC. Always mounted the cap right on the rotor terminals. N2TK Tony When I recently asked about a sluggish HA
I used to have weird swr problems with the original BN-87 balun. Replaced it with the BN-4000B balun and things settled down. Also changed dimensions on the driven elements per Roger Cox. - RDE2 from
This is forwarded from K3OO as to what he did to ix his C31XR Hi Tony, It appears that a lot of the folks I talk to have the same problem with 15m resonance with the c-31xr. I shortened my 15m driven
Looking for a tribander to replace the C3 that was destroyed when a tower fell over during a storm at the contest station at V26B. Does anyone have a TH6, TH7, C3, C4 or similar type tribander that t
I use a TB3 with my 2" 4130 mast. It slipped in fine. You don't do anything to the TB3. Tony N2TK Hey all! I'm curious about the Rohn TB? thrust bearing (2" model): 1. How tight is the 2" fit? I have
Still looking for a tribander, such as a TH6, TH7, C3, C4 for our contest station at V2. Our C3 was destroyed when a tower came down. If you have one of the above, or similar antennas available, let
I have used two different types of tie wraps - those that don't say anything on the bag and those that say "UV light resistant". The non-marked tie wraps get brittle and basically fall apart from 6 m
19 years ago I pained my mast with a high temp red primer paint (don't remember the brand). Then I put on a coat of aluminum paint. The aluminum paint as come off in spots, mostly where the mast brac
Forgot one point. I first poured some paint thinner down the pipe while rotating it (had the other end taped). Then I poured the thinner out. Was hoping this cleaned the surface for primer to stick.
Has anyone tried shunt feeding by running the shunt wire up the center of Rohn 45 instead of the more common way on the outside of the tower? If this would work it would allow me to side mount some b

Typically the heater circuits are wired with #12-2 w/ground romex cable with a 20A 2 pole breaker. To change the circuit to a 110V circuit, I have done the following - remove the bar connecting the 2
