In a video with Eric taped end of September at Waters&Stanton UK I've
learned that the K4 won't be delivered earlier than end of March or
beginning of April 2020 in Europe. Since I've ordered my K4D with full

Absolutely. The other advantage of a horizontal dipole (or inverted V) is that
it will be far quieter than the wire.
An end fed non-resonant wire installed as a sort-of sloper “works” but is far

Bob,
Bandpass filters at each station will help a lot, but they do not have
infinite out of band rejection.
There is still a huge benefit with single band antennas. My club uses both.
Last Field Day (3F operation) one station got on the air with a
multiband vertical, and all other operators
Fair enough, but it kinda goes without saying that in a group FD with 1 station
per band they'll use resonant, single-band antennas. If this is our best
argument against the 'multiband dipole', then that antenna still holds its own
pretty well in a multitude of other situations.
I have always f
The one "multiband" antenna one can use in a multi-transmitter
configuration is the flat-top with open wire feeders and a
*Link coupled* tuner. The link coupled tuner is a bandpass filter
that significantly reduces harmonic/broadband noise just like the

As usual, there are exceptions to everything. A multi-band beam, such as a C3S

and the antennas are spaced in a straight line end to end with separation

The only issue I've encountered with single band antennas, to staff a
Field Day site to operate 2 or 3 stations per band, and 5 bands, there
needs to be some 10 to 15 antennas erected. Where as a single 135 ft

I don't do field day. I've been using monoband dipoles so far for portable
operations due to cost and weight constraints. They work incredibly well,
and I hope to go out with a high Q antenna for 30m and a long pole to try
end fed vertical. (My long pole seems stuck in the post! Courier emailed.).
