What HF Antenna

Postby DaveP » 17 Nov 2016, 15:30

Im open to suggestions on this topic.
I have a very small garden and have pole mounted my antenna's bolted to my shed, the bolts are fish plated through into 2X1/4 steel. I cant fix to the house as it is timber constructed with an outer skin of slate. At the moment I am using a trimmed for 10 meters Antron 99s, it will tune for 12 and 20, although I suspect not to much power is arriving at the aerial. I am looking for a vertical multi band that will give me 40 through to 10, if possible. The butternut's and Huslers are out of the question as I have no where to plant them. Any one have any ideas on a pole mounted multi band HF antenna, perhaps a GPA set at 20 and tune up and down, rather than from 10 as I am doing at the moment. Oh by the way cant do along wire as to get even a 1/2 wave out it would have to go up and down my garden several times.

Sandpiper MV-10. I have used one mounted ground level and up in the air between 15 and 20 feet and it worked a treat.

Diamond and Hy-Gain make some multi band verticals but I have never used one.

Alternatively buy a Cobwebb for 20 through to 10 and buy an Ampro 40 to go above it.

Also take a look at what was SE-HF360 as a cheap option, i have one mounted to a clothes pole in my garden results so far are good. Although i would like a cobwebb too as having read plenty about them they are very good.

:) my suggestions 1) cobweb
2) ten metre fishing/flag pole antenna with counterpoise
3) inverted L
4) if there is available space a loop

I use a Sirio 827 & my FT920 can tune it on 40m -20m - 17m - 15m - 12m - 10m, it's 4m off the ground and has managed VK's using WSPR @5w

I have a full size and a 1/2 size g5rv mounted on a fiberglass fishing pole with the feed point in the corner (coincidentally in the north).
Worked Australia and New Zealand on both with under 100w

Thanks for the replies, I have checked the suggestions out and decided to start off with a windom type wire. I got the Moonraker short 20m through to 10. I managed to get it up 25 feet and fitted a 10 wind 4.25 inch diameter balun, using mini 8 coax. It is running down my garden with the ends facing east to west and broad side on north to south. SWR is not as good as advertised but at 3 it 1 on all bands easely tuneable. I have only used it for 1 hour on Thursday afternoon this week as at this time of the year I have so much to do. Any way, conditions were prity bad with a high level of QRM on 20 meters, however I had 3 contacts, the first a 5 and 7 into Lithuania the second was a 5 and 10 over into Italy (No surprise there) and the third a 5 and 8 into Georgia USA. All in all for 40.00 a good wire antenna at only 10.5 meters long.

Dave if you are stuck for space but can find a 12m run, this is available soon

Thanks for the lead to the gwhip site, it looks very interesting, however my garden is only 9.5 meters so the only way I could accommodate the end fed 3 bander at 12 meters long is to run it through a isolator at 7meters and bring the 6 meters back and form a V. When they open again in January I will give them a ring and seek advice. The Windom fits simply as the total length is 10.5 meters but of course it is one third X 2 thirds fed, so the (Aproxamatly) 7.5 m run goes easely down the garden and the 3 m leg is at 90 degrees across the garden. Used it today for around 1.5 hours and worked 2 stations in Croatia, one being a YOTA, A YOTA in the Netherlands, a station in Hungary and one in the principality of San Marino. All giving 5 and 9/10 reports. However im still keen to look at the gwhip one if it can be inverted into a V. Once again thanks for the info.

I contacted gwhip and posed my question, as to weather the new 12 meter long 40 through to 10 end fed wire could be in a V or L shape. I got a very nice reply. But unfortunately it has to be straight, any bends or angles would put the resonance of the whole antenna out. Looks like I will be using the Windom. Such a shame as the gwhip is such a well constructed areal I would love to have tried it. Say lave {bnghd}
