Maybe I missed something. I looked on that web page but see no picture of the Heath tuner... _______________________________________________ _______________________________________________ TowerTalk
Greetings, My local city Building Department wants me to prove that my proposed (24 foot) tower installation with a 3 element beam for 17m & 12m can withstand 139 mph winds before they will issue a p
Many thanks for the explanation, Joe. In considering whether to forge ahead, do you have any suggetsions about finding some help making the claculations for this? It's a no name brand aluminum tower,
Allstate even went so far as to get in trouble with the state of Florida for their unethical practices. It was mostly kept out of the media. People have no idea how MOST states Insurance companies ar
I have not heard of this concrete ground before. Is it made with conductive concrete? Best regards - Brian Carling AF4K Crystals Co. 117 Sterling Pine St. Sanford, FL 32773 Tel: +USA 321-262-5471 ___
910 micro Henry sounds like a very useful loading coil to me!! I have had no difficulty using a ground rod as a counterpoise to my vertical. In fact it's done extremely well. I added two radios becau

My 5BTV is like the Bumble Bee that defies 100 years of aviation theory that says it can't fly. Of course a pair of 3500ZGs can help with that. It was an old recommendation from Wayne Green. Best reg
The advice varies about this considerably. This week is the first time I've even heard of UF ER or conductive concrete! The professional experts that I know recommend putting a 20 to 30 foot ground r
So far I am not convinced about using concrete. I'm going to do some resistance testing on the concrete in my yard. Best regards - Brian Carling AF4K Crystals Co. 117 Sterling Pine St. Sanford, FL 32
I suspect it's not as conductive as some may have us think... Best regards - Brian Carling AF4K Crystals Co. 117 Sterling Pine St. Sanford, FL 32773 Tel: +USA 321-262-5471 ___________________________
Empiricism is probably my greatest strength and perhaps weakness in my survey of concrete possibilities. I like things that work rather than what is calculated to work. I will probably not use or nee
LOL - good one Patrick. I am just waiting for one of the folks here to tell you where to send YOUR opinion (grin!) But seriously I would like to know what your ohm-meter readings are. Bry AF4K ______
So the text books say.... However some of this is counter-intuitive and very counter-empirical. Best regards - Brian AF4K _______________________________________________ _____________________________
I did mention, it's a 5BTV that breaks all the rules. I love it. It outperforms most other antennas I've ever used. Must be the wonderfully wet Florida soil or something! Best regards - Brian Carling
Somebody could conclude from this that you should not bother grounding your equipment in the shack if you using a dipole or another antenna that does not work against ground. However I can think of s

UPDATE and QUESTIONS Thank you for the guidance and help you guys provided so far. I have decided to switch to using some tower materials of known specifications rather than the three 8 foot aluminum
I need some also! 3 in fact! Where can we buy them or even mail order them please? Best regards - Brian Carling AF4K Crystals Co. 117 Sterling Pine St. Sanford, FL 32773 Tel: +USA 321-262-5471 ______
Most of us have that already in the form of out coax feedline's outer conductor. Typically this is grounded at the antenna and also in the shack. Am I right? Best regards - Brian Carling AF4K Crystal
