A 60' inverted L works OK but certainly the more vertical element you have
the better. In either case you need a good ground system. I am curious what
the efficiency is of a coaxial inverted L? I believe that the selling point
was increased bandwidth.

GD,
For quite a few years I have been using a 160m coaxial inverted L antenna.
CQ
Magazine Aug 84.
Have the vertical section about 60' up and the rest on the horizonal.
There
are 14 full size radials.
While the SWR is and has always been fine, lately I have been wondering if
the
antenna is "to quiet".
Am thinking of raising the vertical section higher and getting the FP about
10
ft above ground also changing the raidials to above ground.
1. Wonder if anyone has direct knowledge of the coaxial vs a single or
parallel wire inverted L?
2. Would raising the antenna up 10ft be worth the labor?
Thanks in advance for your input.
73, Chuck N7BV
