Post Radials - or more precisely lack of
I have no means of laying any radials out in my yard, all flagged and concrete, and a very small footprint.

I m looking for a HF antenna, which is not too obvious, a mag loop is not an option due to visibility from all directions.

Maybe a vertical of sorts, which I could construct myself.

Any suggestions or pointers please.

You might like to consider the following commercial multiband verticals - none require buried radials.

Cushcraft R6000 covers 6, 10, 12, 15, 17 & 20m. Cuschcraft R8 as R6000 but includes 30m & 40m

see www.cushcraftamateur.com

Also MFJ Hygain AV640 covers 6m to 40m.

see www.hy-gain.com

I am NOT endorsing any of the above - suggest you look on eHam.net / reviews and form your own judgement.

Hope the above helps

Thanks for your replies, Cobwebb type antennas are out of the question, I will have a look at vertical options. It will have to be mounted off the house, probably against garage wall.

I used an R7 for a while, mounted in, and poking up through a tree, and it performed very well indeed, returning an very good report from the Falkland Islands (circa 8000 miles) on 17.

If has four 4ft fixed stainless steel radials providing from the base mount.

Not a cheap option now, but good build quality, and effective.

Oh yes, why did I stop using it?

Because the tree obscured the view from my observatory from where I pursued my interest in astro-imaging, so I felled it.

Assuming that you live in the same traditional 'Coronation Street' - style house that I was raised in, then the 'Inverted 'L' is the most obvious answer.

They will tune happilily against a big earth spike if you can't accomodate radials. I was lucky, because I could plonk mine on the little square of bare ground left when the old outside bogs/coal-holes were demolished, but I'm sure it would be easy to either lift one flag or drill a hole for the spike.

Also, you could make the mast out of a fibreglass pole, and swing it upright when you are using it, then have it lying on a few brackets along the dividing wall when you are not.

And of course nowadays we have the remote autotuner, which we didn't have then :)

I tried an inverted L couple of years ago, also th 66 feet wire. But due to proximity of house RFI was a major issue. I think I will be left going down the vertical route.
I operate from garage,

There is a telegraph pole at the back so that don't help either.

Will probably end up with a portable vertical until we hit the lottery and buy a house with antenna space.

why have you got a chuppa chup on your roof :scratch: :lol:

maybe a ""gutter" loop could be strung around and over the roof??

Maybe a "Gap Eagle would work no radials required.

What about a pole bolted with brackets onto the garage with a cobwebb on top? only 8 foot square, looks like you got the room.
