I have a 135 feet L-antenna (70 feet vertical, 65 feet horizontal) for 160
meters with about 20 ¼ wave radials to it. It works well on 160 m and is
also resonant with low SWR on 24 Mhz and 28 Mhz. I now wonder how does the
elevation and azimutal pattern look like on the latter two bands? Is there
any low angle take offs or is it a cloud warmer on the 24, 28 Mhz band?
Can anyone help me with the modelling since I am not an expert on this and
do not have EZNEC 3 or 4. I do happen to have the EZNEC wire model file for
the L-antenna from ARRL Compendium if that helps.
Thanking in advance!
