Hi Clive !
(and All)
Nice photos.
I was also thinking to make 80m loop,
I had one there abt 20 years ago, but now there is
higher trees and not yet clean space for full loop.
FC40 will get loop connection after some woodworks.
My town QTH is in flat and I have 41m long horisontal
wire between similar houses, down wire abt 21m
to balcony where AH3 (the icom tuner) is installed.
Distance between houses is 60 m and yard is 80m wide.
So, there is enough space for 160 or 80m loop. One of
this summer projects is to try 160m loop with FC40 at
cottage to see how loop works with higher bands....
How is your FC40 tuning your 80m loop in different bands?
How is the loop working ? What bands You use most?
Is the feeder windowed 300 ohms ? Your ground ?
This weekend is for end fed wires. ..I got new thought
while writing.. next wire will be "G5RV wire". It means
radiator 13,5m + 10m and counterpoise almost same,
just a bit longer. 10m comes from the open wire section.
G5RV has been my favorite since I started HAM hobby .
Last weekend test was 40m, 12m, and 8m long wires.
23m wire will match nicely to that serie.
FC40 manual is telling that with 20+ meters tuning range
is from 1,8 to 50 MHz. It will be intresting weekend..

Hi Rami
i use an 80m horiz loop in Espoo, see the 'photos' pages in the
yahoo groups.
There's also an excel file someone posted with already tried and
tested wire lengths from the Icom tuner, which work!
good luck!
Cheers

Hi all,
Finally I got my boat on the sea and I was able to start
testing FC40 at my summer cottage, Cottage is in island and there
I have quite good possibilities to test different wire antennas.
Radio is FT897. Feedpoint abt 2m from ground, FC40 on cottage wall.
Grounding was not very good, it was connected to cottage electrical
earthing loop with 2,5 sqmm 5m long cabel.
first wire was abt 40m (132 ft )
(vertical part abt 8 m, rest horisontal position )
160m OK
80m NOT
40m OK
30m OK
20m OK
15m OK
10m some areas OK
second wire was 8m (26 ft), mostly vertical
160m NOT
80m NOT
40m OK
30m OK
20m OK
15m OK, not perfect
10m some areas OK
third wire was 12,5 m (41 ft ), mostly vertical
160m NOT
80m OK, not perfect
40m OK
30m OK
20m OK
15m OK
10m some areas OK
I just made tuning testing, only one qso.
Coming weekend more testing, different lengths, better ground
and if time enough, also counterpoises for every band...
