Dear Claudio, thank You for answering. I know that the gain of an active antenna will increase by 6 dB average by doubling its height. I also have an active Antenna installed, but so far at a height

Dear HaJo, I can not find any reason to believe that the same ERP radiated from 2 antennas with the same radiation pattern could produce different field strengths. But I am far from an antenna specia

LF Hello, an interesting discussion. How about high angle radiation from the toploading wire at DI2AM? As I understand it the shape is more or less an inverted-L. 73 Paul-Henrik Quoting Rik Strobbe <

Dear Rik, thank You for your contribution. Especially your last sentence is interesting for me because this may explain the success of MF-stations operating close to the coast. Another example for ex

Dear all, ok about this neat aerial. I have also heard GI4DPE quite often and had a crossband qso 600m/80m with him. But is "neat" really the best way? This question causes me to put a question here

If your antenna is an active one, like mini-whip, I agree. You can find some info about "height gain" in this paper, page 7: SCHWARZBECK MESS - ELEKTRONIK, "Calibration of Vertical Monopole Antennas

Dear HaJo, But in general I feel that antenna height should not be disregarded. Even with equal ERP sky waves may develop better from higher aerials. HW? I guess that the only cause that 2 antennas f
