one site that stated FEP-9 could be used outdoors. All the other sites mention nothing about outdoor use. 142 has been commonly used for baluns on VHF yagis for many years. I don't recall hearing any
Try climbing 75 feet of Rohn 6, then 10 feet up a fixed aluminum mast that is guyed 20 feet above the tower. The tower flexes and twists, the mast flexes. Fortunately I will be doing that for the las
Mike, The best advice if you're not comfortable is DON'T CLIMB. I strongly encourage you to take that advice. However I will relate my story. I'd had some very minor experience climbing 40 to 50 feet
I had the exact same problem until I switched to direct burial flooded RG-6. Never another chewed cable after that. It is laying on the ground in the woods just like the previous regular varieties of
Hi Bob, The labels on my partial rolls are unreadable now, but I am certain the jacket is PE. Mine is not quad shield, just a single aluminum braid shield plus foil. It is nasty stuff to work with an
Yes, exactly. I know much of what I do (not limited to towers) is subject to more possible failures because it's not strictly by the book due to budget. I also know I would probably not be able to re
Yes. The turnbuckles on one of my towers came with nuts on both sides. It has been long enough that I forget where I obtained those turnbuckles. After adjusting tension on all guys I tightened all of
I've been reading the fan dipole discussion with much interest. I have used fan dipoles for many years, as inverted V, common center point with the ends tied off separately. The biggest one (a club p
I would not recommend a parallel/fan dipole with 80/30 meters. I've tried it several times and the 80 meters wire detunes 30 meters. The antenna works as badly as if one simply used a tuner to force
I am far from an expert but every bracketed Rohn 25G tower I have climbed (several) wobbled in the joints above the top bracket. The one that I took down showed major elongation of holes in the joint
I think you're right Jeff. I never expected to see winds in excess of 60 mph here and that only on rare occasions, say once every five years or so. Yesterday I recorded 70 mph gusts. For a while I th
Physical strength is probably the main factor. I successfully ran 1500 watts into an inverted V made of a single conductor from of WD-1A field wire. I believe it is slightly larger than 20 AWG. It ha

Arrow has consistently been the cheapest source of Fair-Rite cores in small quantity for me. They are currently offering the core in question at $3.84 each with free overnight shipping on orders of $
I failed to mention it before, but I find Arrow's prices fluctuate wildly. I always check other places but despite the price ups and downs Arrow has been consistently beating everyone else on small q
I bought a TH-11DX in 2015. I had to resolder all the ring terminals on the wires that connect the log elements to the dual tube feed before even assembling it. There was so little solder on them I c
I have been trying to model this (using MMANA) but I have a hard time getting my head around modeling. I have a full size 40 meter rotatable dipole which I plan to install at 105 feet. I want to put
Initially, nothing but 40/30 will be on the mast. At a later date I plan to add some UHF yagis but the booms will be at right angles to the 40/30. I expect little to no interaction with those. I will
Herb, Yes I have but I consider that an option best left to expert builders or those who primarily want to experiment. I am unable to create any model which shows good SWR on two bands with that appr
Thanks to everyone who replied on and off list. There are several shortened 40/30 dipole designs around. Since I already have a full size 40m element built and would like to believe it is mechanicall
