Hello Thinking on fixed antennas to avoid rotor problems, I have a question/doubt. if I have a stack of 3 antennas (15 mts monobanders) on the same tower, how worst will be to add a second stack of 3
Big problems with that, Jorge. Even if 90 degrees off and I think you won't be positioning them that far off (more like 70 degrees or so?) with only 6 feet of separation (your example used two feet b
Jorge, I took a six element 15 design I had and put three of them with 50 foot spacing in EZNEC Pro. In free space the SWR was as follows, driving all three: 21.000. 1.035 21.225. 1.028 21.450. 1.290
Hi Stan Or maybe a better idea is to have two 200 ft tower, one for Europe and other for USA each one with 3 x 10 mts + 3 x 15 mts + 3 x 20 mts beam at the appropriate height? 73, Jorge De: Stan Stoc
Jorge, One of the benefits of a stack is to reduce or eliminate the higher angle lobes for receive. From the middle of the USA where I am located, it can make a big difference in reducing the QRM fro
Quick switching and the ability to run in two different directions is nice at times but as Stan said it is a lot of work. My preference when operating from South America was to run Europe when it was

All I am saying is that 18 Yagi antennas and the associated switching to cover 20/15/10 in two fixed directions is a lot of work. Jorge, two towers with arrays pointing different directions is a goo
