Post Advice please on small garden antenna HF 80 upwards
Hi all.

I have just bought Steve's G3TXQ antenna and will get it setup when i can find someone with ladders. I am disabled and looking for help please to install it please in the Rotherham area (will pay petrol expenses etc).

I have a very small garden and want an 80m upwards wire antenna. Neighbours are rubbish here i'm afraid and can't use a Scaf Bar. Here is the house view https://maps.google.com/maps/place?ftid=0x487976a9522d1609:0xec83793a609a9bc7&q=9+Cannon+Close,+Rawmarsh,+United+Kingdom&hl=en&authuser=0&cd=1&cad=src:ppiwlink&ei=f8AfUNWCGsi6iAb3zoEQ&dtab=0l

(Sorry i can't seem to find the url to show my back garden with the little yellow man) So turn left so you can see a BLUE car then mine is the one with sat dish, alarm, V2000.

I can go to below my Diamond V2000 where the base is around 30ft (ish) sloping down to the fence which is about 6ft.

Has anyone any suggestions please? Unfortunately due too my disability and illness i am unable to make homebrew antenna's so i guess i have to buy one.

Obviously the better the performance the better and the better the noise level the better. I guess this is one of those situations where you can't have everything.

I can't have a vertical due to neighbours.
Any help would be greatly appreciated please.

Please PM or email bigyun2000@yahoo.co.uk

Bloody hell, small world. I used to deliver cream to your house when it was a food factory and the wife's grandfather used to live across the road at the end old folks bungalow.

Back to point in hand....

Anything you can put up wire wise will be so inefficient it'll just be disappointing and wallet emptying. There's no real room for radials and you can't put up another support. and not even enough room to get 1/4 wave inverted L up for 40m. In fact you'd struggle to fit a 20m dipole in in a straight line.

The only thing I could think of would be a magnetic loop antenna but you'll be retuning every time you move more than a couple of kHz. If you can live with that, it'll be dead quiet though and not intrusive.

Personally though I'd stick with what you're getting. Sometimes you've just got to admit defeat and make the best of what you have which you are doing by getting what you've bought.

Hi Conor. lol, my wife and her mum worked here at the dairy's. These were a last minute build to squeeze as much as possible on the available land. So these houses are very small. We also have the resident ghost (ALBERT) bit of a pest at times, keeps moving things.

Anyway have been looking at Ultimax 100 http://www.ultimax-antennas.com/services.html

Also was wondering about this: http://www.hamradio.co.uk/aerials-antenna-manufacturers-diamond-antennas/diamond/diamond-wd-330s-pd-2600.php Only problem is, i would have to tie it to bottom of Diamond V2000 (Triband Antenna) and use it sloped to 6ft fence.

I think you know the problem with the end feds although people rave about Par Endfedz antennas.

The diamond Terminated Folded Dipole will work as a sloper if you can fit it in with an easterly bias to the signal. I didn't think you had that much room as I was going by Google Maps doing the measuring and the aerial shot is at an angle to your house so masks some of the garden

Just had a measure. It seems the length of the garden from wall to fence is 22ft. I have to allow 18" to 2ft for the distance used by my v2000 antenna bracket & pole. However i have this spare due to the angle the antenna would go.

I could in fact have some kind of dipole as the v2000 is located more or less central to the house and i can have 20ft one leg but only 16ft the other leg unless i have a dogleg. Phew

Just a thought,you may get away with one of these.Easy to make & work well for a small area.

It looks like you could get a 30ft dipole between the base of the V2000 and the fence; feed it at the centre with ladderline, and use a good tuner, and you'd have an efficient antenna for 30m thru 10m. Add some "dog-legs" at one or both ends and you would get 40m thru 10m coverage.

Hi Markd. Just bought one - thanks. Seems it may be the answer. May look at buying the Ultimax too.

Hi Steve. we must have posted at the same time hi. The cobwebb arrived this morning. Due to disability i can't put it up myself so i am looking for local antenna installer. So it's off to the shed until that time. Just bought the M0CVO Magitenna so hopefully that will sort out the lower frequencies. I know it won't be the bees knees but i think that may never come until i move home. Looking for a house at top of a hill with no neighbours and stacks of garden (I wish). I live at the bottom of 3 hills so VHF/UHF is very poor.

M0CVO Antennas MAGITENNA

The easy fix for limited space. Only 7.6m in length this wire antenna with the special matching unit will work on 40m to 6m with the internal ATU found in most modern radios and 80m & 60m with an external ATU. This antenna will handle 400W CW or 550W PEP



Connor has already elaborated on the issues of such endfed arrangements and I too am always very sceptical when phrases such as
"Special Matching Unit" are used in advertising. I certainly would not want to run 100Watt, never mind the quoted 400W, into such an antenna without having some form of RF ground/radial system employed. I believe The Par Endfedz are sleeved dipoles as opposed to
a traditional endfed wire.

I cobbled together a G7FEK type antenna a year or so ago, I had to dog leg it a little to fit in the space available but it didn't perform too
bad at all, certainly up on a 1/2 size G5RV type antenna, and produced a few Asia contacts on 30m CW (5 Watts).

Regards

Nigel,

The Par EndFedz I have seen have all been end-fed half-wave wires with a tuned-circuit matching network at the end. Perhaps you are thinking of the "Mixed-Mode Dipole" made by Miracle Antennas - that is a half-wave dipole, centre-fed electrically but end-fed physically, with the sleeve arrangement you mentioned.
