[UK-CONTEST] 'Remote' radials...

[alannottage at aol.com]

I predict that this will have a skewed pattern Stewart and be marginally better than using a single radial.? I suspect the strap will behave like a single elevated (or on ground depending on it's position) radial.?

Hi all,

Continuing in the 'remote' vein I have a scenario for comment/advice:-

Shack in the garden centred on a decent system of radials trailing round the 
garden and into a neighbouring farm field (sheep, not ploughed!)

Garden is wife's pride and joy so maybe I want to put up a temporary (single 
band) vertical out in the field for a weekend's contesting. So how effective can 
I expect the radial system to be when it's connected to the antenna earth by a 
possibly longish earth strap? If the strap was electrically isolated and 0.25 
wavelenths the antenna earth should be very high impedance and a lousy zero 
potential; by the same token a half wavelength should be fine...?

Also what's going to happen to the radiation pattern in broad terms?

Thanks for any comments,

Stewart Rolfe, GW0ETF
