[ICOM] Icom auto tuners and multiband antennas

[Julio Peralta]

If you have the room I would suggest a 160 Carolina Windom. Icom tuners
seem to be able to match it anywhere in the ham bands. I've used it with
great success as have others that I have recommended it to. It seems to
be a very good performer on 80M as well. You can find info about it on
the Radio works web page.

Hello to all,

Due to a forced change in QTH, I am considering the options of what type
of station I will assemble once moved in there.  My present station
consists of dedicated antennas for each of the HF bands in the form of
dipoles and yagis - I have an AT-500 which I really use to just
'touch-up' the final matches of these antennas which are pretty good,
match wise, to the required band.

My new QTH location is probably going to mean that I will not be
assembling such a station - instead, maybe settling for a multiband
antenna to cover all the HF bands 80 - 10 metres.  One antenna - and
that will probably be it.

My thoughts so far are focused on the G5RV.  An antenna I have used very
successfully for portable operation but have never used much at home and
therefore have never tried the Icom AT series of tuners to obtain a
match.

How do the Icom 'AT' series tuners perform and handle matching such
antennas?  Has anyone out there tried this sort of approach?  I would be
interested in any comments on how they worked out and how any problems
were over come.

Using something like my AT-500 will allow me to also use the IC2KL that
I have next to it on the operating bench - just a bit of help over
barefoot operation.  (Will be a bit short of what I can do with a 4
element yagi as exists at present).

When portable, I use an AH-4 with the G5RV - which works fine with power
levels up to 100 watts but I would like to use the linear amp when
operating from the home QTH and the bands are noisy.

So my question is, how have others found the AT series tuners cope with
G5RV antennas and hose similar to it?

Looking forward some interesting replies,

Des - VK3DMP.
