As you might know, the current that goes into the end-fed antenna
equals the current that goes into the counterpoise.
ONLY if the counterpoise is connected to the same location where the
'radiating' wire leaves the coax. *if you run a piece of coax out the window
and connect just the center conductor to your end-fed antenna then connect
the 'counterpoise' to the radio ground lug as is commonly done, the current
in the counterpoise may be MUCH different than that going into the wire.
Hello Dave,
I supposed the counterpoise to be connected at same location as where
the antenna connects to the coaxial cable (so the cable is used as
feeder only). When you connect the counterpoise at the tuner, the
cable will be part of the radiating structure and, as you mentioned,
everything changes.
Best regards,
Wim
