I am interested in knowing what the detriment might be if you had a 80 foot tower with a large Yagi for top loading within four feet of a 20 foot tall concrete building with lots of rebar and a metal
I'm pretty certain the answer to that question depends upon more factors than you could possibly know or model, and if you can't model it anything else is a guess. 73, Dave AB7E Im not worried abou

Stan, Is the 80' tower guyed or a self supporter? Cheers,James On Thursday, April 7, 2022, 08:56:01 PM CDT, Stan Stockton <wa5rtg@gmail.com> wrote: I am interested in knowing what the detriment might
It will be guyed but, of course, with non conductive guying. _______________________________________________ _______________________________________________ TowerTalk mailing list TowerTalk@contestin

Great start. Been shunt feeding my 116' tower successfully >25 years with a remote controlled capacitor.Easily achieve a 50 ohm load through-out the entire band. Thanks n 73,Jameski5dq ______________
Hi Stan, Intuitively, I'd expect the pattern to be down a bit in the direction of the building. 73, Jim K9YC _______________________________________________ __________________________________________
Is there an alternative? I would agree with Jim but who knows. What direction might be compromised? W0MU On 4/7/2022 9:09 PM, Jim Brown wrote: On 4/7/2022 6:55 PM, Stan Stockton wrote: I am interest
Metal roofs can cause RFI issues but I am guessing that this antenna will work well, especially if you have sea between you and your target area. Can you install an adequate ground system on your pro
EZNEC has a feature to make a XYZ grid of wires, the manual advises less than 1/10wl between them, although I use a finer mesh. So some insight can be gained with the roof insulated from ground (no w
I would be quite pleased if it only attenuated signals a small amount and only in the direction of the house. That would be from West to South going CCW. Currently my tower is 30 feet SW of house and
The hard part is how the metal roof is grounded. With NEC4.2 a buried ground can be set up, not so in NEC2. Connecting the roof via something (mesh, separate wires) can take a lot of time to set up
Huh? So 55 feet for spacing and segment length and about 17 feet for the diameter of the wire for 160m.??? My house isnt big enough for two wires in a model. Sent from my iPhone _____________________
