[UK-CONTEST] CQWW SSB contest

[Callum M0MCX]

I was tempted to come "off list" for a reply, but I'm sure there are plenty
of us in this "wires under 30 feet" category that are interested.

This is my antenna orchard:

a) 40 meter full size horizontal three sided delta loop (Permanent) at
gutter height, 16 feet or so.
	- 40, 20, 15 and 10 meters with perfect match on 40 and 20 
	  (Needs a little bit of ATU or outboard tuner for 15 and 10)

b) 80 meter full size "compressed" square loop for 80 meters with a loading
coil in each corner to make it physically 60 meters in circumference (15
meters each leg) (Permanent). On average, this is slightly higher than the
40 meter loop but only by maybe 2 meters. This is what I use for 80m Club
Champs. Can do 160 meters by turning it into a Halo by taking out 2 meters
of wire opposite feedpoint (which is inside middle of loft!) but difficult
to QSY back to 80 again (lower, fiddle with some copper wire etc..).

(Both loops fed with separate coax and a balun)
 
c) Coax fed, twin dipole (called a fan?) in loft with loaded 40 meter dipole
and 20 meters off same feedpoint
	- Can also get 15 meters with this but it's noisy, loop is better
	- Will replace this with 20, 15 and 10 fan dipole & 1:1 Balun one
weekend this Winter

d) Not used this year: Elevated radial Qtr Wave vert peaking at 50 feet -
storming for 40 meters. Bit specialist for an all band entry I guess

e) Not used this year but works great for restricted all-band: a G5RV at 40
foot using two 7 meter fishing poles connected together. See here:
	http://www.mccormick.uk.com/g5rv/40-foot-G5RV.jpg

Let me say that the mini-G5RV was by far the best antenna out the lot in
tests during the summer for any band and I would have used it but ran out of
time coming back from Ireland. I would have thought it's not very storm
friendly either.

I'm now hooked on restricted all-band entries so I'm probably going to put
up a small mini-beam again for 20, 15 and 10 off a T&K bracket / 6 meter
pole - anyone else do this?

Regards,

Callum.

Callum, 

I have the same problem with garden space for HF antennas. It's
verticals or nothing, although loft wires are a possibility. Can you
let me know what you have please?

The only reason I have the 'VHF' tower is I was the first person to
move in to the row of new houses, and applied for planning permission
before anyone else moved in!

The biggest aerial I have up is a 5-ele for 50Mhz which has proved
very good in Sp-E and contests. Took a look on Google Earth and it's
enormous! Perhaps a cobweb or spiderbeam for Christmas?

Cheers

Graeme.

Although I'd love to be a bigger station, current house style
precludes any
investment in antennas. I did have a small tower but contesting in
towns is
bl**dy impossible in the UK.

I entered the unofficial category "Wires under 30 feet" with two full
sized
loops and various loft wires for 547 Qs and 153,000 points (all
band). Qs
>From 160 to 10:  20/128/121/148/59/70
