A number of articles analyzed 160m verticals by simulation. Once the height was lambda/8 and the number of radials >= 16 (buried) or >=4 (elevated), the difference in gain was at most a few db. I ope
Hi Ignacy, Salt water is very special! In a salt water environment potentially the entire Fresnel zone -- where as much a 6 dB of gain is obtained from ground reflection -- is in a highly conductive
So true, my AM broadcast station location with 120 330ft radials does not hold a candle to the same InvL antenna at the beach with two radials. I am about a mile inland from the beach. Too far for
Actually, I'm rather sceptical about the accuracy of theoretical antenna modelling software generally on 160m. (as per my recent discussion on a well-known Forum) I'm not convinced that the various p
If you really want to get accurate ground modeling, you need to follow N6LF's procedure. He installs low dipoles at various heights over his ground and measures their impedance and resonant frequency
Exactly! How can you know what your ground is REALLY like, especially when you go underground? (and even if you knew, how could you model it?) I'm really not interested in trying to get an accurate m
Hi Roger I used a dipole for several years too. Actually took me 20 years to work my first DXCC on 160m from SPaulo Brazil using them.. Here is the thing, your horizontal dipole is not 100% horizonta
