I just looked at my XM240 in EZNEC at 1.8 MHz and the gain, straight up
with the source at the antenna, didn't look too bad, but when I figured
in the line loss for my RG213, the line loss was 34 dB. Now maybe if I
could open the shield connection.....
It does work as a 160 receive antenna (better than a low dipole) but not
nearly as good as an EWE, K9AY, or beverage.
