It would help to know the exact model, but from what I could see from
the website, this is similar to the Palomar end-feed baluns, though you
can transmit on the Par Electronics version. The performance should be
similar to a long wire, but more efficient since the transformer will
improve the match.

Since you are not transmitting, more wire will probably improve the low
end reception, though most of those ham baluns don't work well in the
AM BCB or lower.

Hello folks,

I have a question here... I recently bought one of these excellent Par
Electronic EF-SWL antennas.

As the supplied radiator can be disconnected and another wire be hooked
onto the 9:1 transformer, I was thinking to give a go at hooking up a
150 foot length of wire that I have on hand. My question is this: in
hooking up an alternate wire to the transformer, would the antenna lose
its characteristics as a 1-30 MHz antenna? Would an antenna tuner then
be required?

Very curious for info on this. I'm afraid I don't know too terribly
much about antenna theory.

Thanks in advance for any help provided,

Junius
