[ICOM] G5RV Dipole

[Tony Lord]

Thanks Des,

Sounds like it works well for you! See you on 80m, G5RV to G5RV??

Hello to all,

I would like to add my two bits also.

I have used a G5RV (minus any coax connected to the twin feeder) with the
AH-4 feeding it directly at the end of the twin line.  One side of the line
to the ground connection and the other to the antenna connection.

It works and tunes fantastically on all bands between 160 and 6M.  Yes,  you
would be surprised how well it works for 6m SSB!  On 160, it will tune and
work, I have worked both VK5 and VK7 from my QTH in VK3 with good reports
both ways.  Of course on 80, 40 and 20 it roars like a lion.  I use it for
portable or field work, not as my home station antenna but I have been so
impressed with the performance of my field day setup that I am intending to
put up the same arrangement here at home as a secondary antenna system that
will work all bands should I wish to have two bands going at once.  Does
happen sometimes!

I recommend it although the purists would say it is not the best for this
reason or that.  Fact is it works well.


73,  Des - VK3DMP.

Tony,

I sucessfully use a G5RV on almost all bands (not too good on 30 M),
along with other antennas. If you are using a full-sized G5RV (102'
flat-top), I believe you are giving up a lot if you tie the leads
together. I haven't used an AH-4, but have used a similar (I guess) SGC
SG-230 with the center conductor of the coax on the antenna terminal and
the coax shield on the tuner ground post. It may work even better,
especially on the higher bands, if you have enough coax to make a coil
of half a dozen turns 6 " in diam right before the coax connects to the
tuner to limit current on the outside of the coax.

Nothing wrong with hooking the leads together, but you end up with a
"capacitance hat on a vertical" and the antenna is the outside of the
coax (in my house running through the basement) and the open wire line.
If you have high conductivity ground around your house (swamp, ocean,
etc.) and a good ground connection, and a short run to get outside, it
may work well. At my house feeding the coax as I describe works much ,
much better.
