[Antennas] 40m Antenna Ideas

My Moxon back home in 4S7, is supported by my organic towers (Coconut palms)
and is 45' at one side and 35' at the other. I have no problem in working
NA, South and Central America with 100w. Even though at a low height, the
performance never ceases to amaze me.

The day I put it up I got unsolicited "better" reports from people who knew
my signal with a dipole at the same height. So, yes, it sure is worth a try.

73,
Ron, 6Y5/4S7RO
