Antenna Work

Since I moved to this QTH I have not been that happy with my HF antenna. At first I put up a half size G5RV antenna and added an inductor to each leg to allow it to tune up on 80 metres. That lasted a few months but after a while the antenna wouldn't tune, try as I might i could not find out why, eventually I replaced it with a home made doublet.
After having my shed demolished I lost one of my antenna supports and for a while the far end of my antenna was simply tied to the fence.Earlier this year my next door neighbours were having some work done on their garden. They removed an old metal pole, 4 metres or so long which they had used to support a washing line. They offered me the pole, asking if it would be any use for my antennas. (I am lucky-I have good neighbours). Of course I accepted the pole and set about making use of it.

First I dug a hole at the end of the garden



And placed the old washing line post in it, filling the hole with concrete.

I now had a "Stub mast" which would form the support for my new antenna pole. 
I then ordered a hinged bracket from a seller on Ebay 


Yesterday I had a 20 foot (approx 6 metre) thick walled aluminium pole delivered and today along with a local Radio Amateur friend we put the whole lot together to make a decent antenna support.


There is a pulley at the top of the pole so the antenna wire can be easily lowered or the whole pole can be easily dropped using the hinged bracket which is attached to the stub pole. We also installed a new HF antenna the "Western HF10 " which I bought some months ago.




Here you can see the shack end of the antenna (the wire is below the VHF/UHF colinear and above the TV antenna)

First impressions of the new antenna are good. It seems very lively particularly on the higher bands and I also had some good reports on 40 metres this afternoon. I will write more on this interesting antenna when I have had a chance to fully test it but it does seem a significant improvement on the previous wire.

  3. Get to see the new antenna is up and running very nice shots of the job as it progressed. Do post more reports of how the antenna works out.
