OSHF-80 80-10m Windom Style Off Set Dipole Antenna

I am completely new ham radio operator, although I passed my City & Guilds exam in 1971! My garden is reasonably large but an awkward L-shape. I was thinking that I'd need to use a long end-fed wire but friends at the radio club were dubious as they said it would be noisy: they suggested that a Windom-style antenna could be the answer, so I plumped for this OSHF-80, and I'm very pleased with it. Unfortunately it doesn't come with any instructions, but there is plenty of general guidance on the internet and it was easy enough to fit. I fitted pulleys onto the top barge-board of the house and on two conifer trees at opposite ends of the garden and threaded nylon cord through the end insulators and the balun to winch it into place. Only about 8m agl, but I am picking loads of continental traffic on the 80, 40 and 20 m bands on my new Yaesu FT-710. So far I haven't risked any QSOs!
My main concern is that the terminals for the aerial wires and co-ax on the balun don't seem all that weathertight. I've sealed them with self-amalgamating tape and I think a slosh of bitumen paint might be needed too. The two 'key rings' that hold the aerial wires to the balun (and which I used to suspend the balun) don't look tremendously strong - the 26 metre longer leg is quite heavy and needs a fair tension to keep it from drooping.
All-in-all, I'm delighted with the item and hopefully you'll hear me on-air soon.

Good quality wire.
Heavy duty.
I installed it easily.
I have coated the terminals with petroleum jelly to keep the moisture out of the connections.

I live in a town where noise is S9 permanently ,I also have trouble with neighbours not liking aerials around the garden. I purchased the Moonraker 80-10 OSHF and installed it in my loft space. Ran 20 meters of RG213 down to my icom 7300 and MFJ 993B. Powered on and BINGO. It tunes up on 80-40-20 with almost no work from the ATU. For the first time in 4 years, I can now work HF. I regularly chat with an Morocco station on 17MHz with a 5-9 +10 report. I can now work DX as well. This Moonraker dipole is very well made (I use all moonraker aerials) with high quality radial wire. A must have, if you want to work all HF bands with low noise and a good SWR.

In the space of one year I have worked 104 countries including the Falklands, Australia (short and long path), Chile and Japan, All on 50 watts using this antenna at a height of 10 meters. The best £60 you will ever spend.

I have erected this antenna at a height of only 5 m to be used as a temporary installation,
The performance is so good that it is now my main antenna and I would recommend it to anyone who wants a simple multiband antenna.
Good quality and value and loads up really well with a low SWR using an ATU.

Having returned to amateur radio after a considerable abcence I have had to start from scratch with my HF antennas. I had been reading some online articles on off center dipoles and the windom design in general and decided that this moonraker windom look like good value.
Boy was I right!

The entire system looks and feels very well constructed and is supplied fully configured.

One thing claimed for this antenna is that it will tolerate being bent should a full straight run not be possible and that has proved to be the case for me, the final 15/20 feet of my installation being taken at right angles along the ridgeline of a garage.

The system tunes very quickly using the internal tuner only on my ic-7600 and there are now so many signals that its hard to find a free channel to call CQ!

The most striking aspect of this sytem is its very low noise level compared to other antennas. Signals really pop out of the background and many stations that would hardly be above the noise on other wire systems are now perfectly readable.

If you don't have room for the full 80-10 windom I'm sure the shorter 40-10 would be just as good so like me take a chance and try one of these you won't be sorry.
