Post 6M Antenna
Im planning on making a couple of antenna's this year and looking at maybe a delta loop for 6m or maybe convert an old 11m GPA type for 6m any ideas, plans or suggestions would be very much appreciated
Thanks

I guess it depends on where you can mount it and what sort of gain you want.

You can make a very effective 6m vertical from a bit of wire cut to 1/4 wave and a piece of non-conductive pipe or fishing rod, plus a few radials, or ground mount it. A horizontal wire dipole will work well too. Or if you want some directivity/gain, I know people who've used Moxon's to great effect.

Or you could go the whol hog and get some very large yagi's like some of us :D

When I first took an interest in 6M I used a vertical.
It produced some good QSOs, when there were strong ES but, most of the time the band seemed dead and I was rapidly loosing interest.
I had a rethink, on the grounds that I wouldn't consider using vertical polarisation on any other VHF band, why was I bothering with a vertical on 6M?
A 3ele Cushcraft Yagi was obtained and the band came to life.
The 6M UKACs were a lot busier than previously indicated.
A/B tests were conducted, switching between the vertical and that small beam, which confirmed the initial indications.
Now I now use a 5ele Eagle.

Cheers

Tony

I to run a 3 ele cushcraft and with luck will be upgrading soon to a 5 ele cushcraft good thing 3 ele cushcraft isn't huge and isn't that bad either in the sky.
As for the conversion for old cb 11m aerial to 6m there are lots of plans and idea's on the web I did ask on here being lazy but after a search there was a few idea's and dimension's and again isn't to large but no-where nr the pick up of the beam

I heard West Africa the other week on a ground-mounted vertical:

But you're right, a yagi will give you much better success, but you need a mast, rotator etc.

All comes down to what you want to achieve. I ditched my 5 ele a couple of years ago because it didn't have the low angle of take-off needed to get the real long distance stuff. Now got a long-boom 6 ele LFA and the multi-hop stuff comes in much better - A4, A6, Caribbean, W0 etc. But that comes at a price, manouvering a 21ft yagi onto the mast without breaking it is a bit of a challenge. ;)

It's the cross polarisation loss that's critical for tropo contacts.
With ES the polarisation is less critical but having a beam helps to reduce interfering signals.

I aggre the beam makes things so much clearer but also noise level drops so improves dx contacts

Let us know how you get on with it as the 6m Es season hots up. I was gutted to take down my 5 ele in the Es season in preparation for moving house, but the temp loft dipole I used instead produced a surprising number of QSOs.
