Leigh,
My doublets work great on the higher bands. In theory, the lobe
configuration does changes with wavelength n of the wire, so you have
roughly 2n lobes. But you also get some gain, and, more importantly, a
lower peak angle of radiation. You can read all about it in W4RNL's
great
The 80 m dipole feed with ladder line and a tuner can work well even with
multi lobes on the higher bands.
See any edition of the ARRL Antenna book or handbook for typical patterns,
or www.cebik.com antenna web site for patterns. If you take into account
the lobe directions you will have fine

I appreciate your interesting posts.
As Ron says AFSK is as clean as FSK if AF in level is set properly.
Last week end I enjoyed CQ WW RTTY contest with QRP K2 (5W)
One of major problem was that AF in level must be re-adjusted
each time when I change Band. This is not in the case of
Hi Guys, my main rig is a K1 feeding a multi dipole for 80/40/20 with no

Hi all,
My base station rig is a K1 that I did not build. Is there an easy way to
determine the actual transmit offset? It doesn't seem to be available from the
menu.
The manual section on offset adjustment says to place switch S2 on the bottom
of the rf board in the test position. Is
While the G5RV has a lot of advocates for multiband use, it works much
better if you bring the parallel feedline all the way to the tuner. When
used for multiband, with coax and the matching section, you will likely find
a higher than desirable SWR on the coax except on 20 meters. I have found
Martin,
Before going to a G5RV, I would try feeding your 80 m dipole with 450

What is the difference between the G5RV and the twinlead-fed 102'

Your multi-dipole will be more efficient on 80 meters, and can be fed
directly with coax and no tuner. If I were in your shoes, I would leave

Charles,
With dual band close spaced beams, everything interacts.
You can try adjusting the wire lengths by the percentage you were off your
target frequency, or just operate them as they fell. They will vary with
height, and there is no compelling need to have them exactly resonant in
cases
Certainly, traps and baluns may contribute some losses as well as loading
coils may.
Tune losses in a decent tuner are pretty low, unless you are trying to match
outside its design range.
There is no advantage save not having a reactance term to match out, to
having resonance on the antenna.
hi Aki - absolutely right - for contest situations, it is especially
useful to not have to worry about readjusting the radio when changing
bands. But even for casual operating, its nice to be able to set the
mode and go, without having to make adjustments.

The G5RV may work well, but I doubt if it'd work better.
For most of my Ham career my mainstay antenna has been a doublet. That's a

currently only about 50 feet) and as high as I can get it. It's fed with
