I am sure this subject has been beaten to death many times but I am not finding all of the wisdom I seek either on the bookshelf or in the archives of this list. I have a TH-11DX at 100 feet. I plan
Based on several responses thus far it would seem I asked a stupid question or at least one which is not possible to answer. The reason I am not finding articles with general advice on stacking 40 an
This is good 50 ohm cable, though I wonder if they really have the long discontinued LDF5-50A. The $13 connector fits the RFS Cellflex 1/2" cable. Connectors for 7/8" are $30, still not bad. I have u
OK, I will bite since this is a pet peeve of mine. I have seen this recommendation a thousand times from hundreds of people. I haven't tried for a few years but prior to that they refused to sell to
As hams it often comes down to doing what you're comfortable with, but... In 2007 I took a small hit to one of my towers. Lightning jumped a 3 to 4 foot gap between disconnected coax cables and equip
Will it work to put up an inverted V with a vertical reflector behind it? Would rather not put up 2 verticals becuse of the radials needed. Probably not, but I will second the idea of adding an inver
Would anyone have pictures of a coax connection you've taken apart and found coated or filled inside with that powder that tells you water HAS been in there in the past? I need it today or tomorrow.
I'm not sure stained is the right word but I have seen this more than once... and wish I'd had the foresight to save at least one for future reference. They were male/female pairs that when taken apa
I trammed a TH-11DX to the top of my 100 foot Rohn 25 tower last year. I did this alone with no help and found it relatively painless. I would have appreciated some help pulling the rope! I STRONGLY
My rotator cable to the southwest tower is buried (250 feet) since 2006. It has some splices, but no problems yet. Each wire at a splice is twisted and soldered, then wrapped with butyl rubber, then
Comments interlaced below... If I ever find a stone here that wasn't placed by man, I may die of shock. I live on pure sand with a naturally accumulated thin layer of what passes for topsoil over it.

Purely anecdotal, but... I have been using the same 7 element, 33 foot boom 6 meter yagi for over 12 years. During that time I have had it at heights of 30, 70, and 105 feet. 30 feet worked very well

Maybe it depends on local weather, atmospheric contaminants, etc. I have had two varieties of very cheap (from eBay) F-female to UHF-male adapters on my Beverage system for 11 years without a problem
If you have a period correct replica of a 1920s transmitter on display in your living room (doesn't everyone?), polishing the coils periodically IS a great idea. Also, handle them with cotton gloves,
I'm sorry but that is like asking why would anyone spend so much more for electricity to run ham radios instead of a cell phone! Many people here in Maine use grow lights to start vegetables for outd
