One other thing, I see, is that End Fed Dipoles
have a extremely high impedence, and hence a very

Then you have to have a pretty good tuner..
Along with whatever losses it provides..
I avoid tuners if at possible. None of my
everyday antennas use one.
I have a 989c, but I mainly use the wattmeter,
and switch..
The tuner itself sees little use. Probably has
spiders inside.. :/
