Does anyone have suggestions or critical commentary on the idea of "guying" a 60 ft alum monopole (with 10 ft dia top hat) using horizontal lines attached to two trees - one on each side of the monop

Bill: Take down the elevated radials. Having the elevated radials above the radials on the ground will buy you nothing but potential headaches. I have never been a believer in elevated radials. They

Do I think trees impact the antenna in a negative manner? Sure I do. So do many other things. How much is anyone's guess, but any amount it hurts is certainly meaningless when compared to not having

With elevated radials near earth there can be a dB or more FS reduction when the feedline shield is not decoupled. This says nothing about the unwanted coupling of noise into the antenna, or RF into

The MFJ-1025 does not have an internal preamp. Some radios, in particular the FT1000MP series, provide an RF OUT and an RF IN jack on the back of the radio. The RF IN jack can be selected from the fr

The MFJ noise cancellers require the the signals from both antennas are equal level. That means that with the 1025 that the "noise" antenna needs a preamp because it is usually a smaller, non-resonan
