Custom S9 31 foot Vertical

I bought a 31′ Jackite pole off of ebay for $59, and then soon realized that it was the same pole they use for the 31′ S9 Vertical and Eagle One. In the end it is probably cheaper to just buy the S9 vertical.  They have them for $95 on cheapham.com.

I found these videos on youtube walking through the steps of assembling a S9 Vertical:

So I ended up putting it together and attaching it to the chimney at home.

The noise level was close to S6 on all bands so I thought I’d try it at the office. I just used the chimeny mount I got from Fry’s for $20, and bent it so it would work on the exhaust pipe and used 4 20m radials, and 2 40m radials.  The noise level was closer to S4 in the Whittier, which was better, but it was still noisier then the G5RV jr, so I took it down.

I reduced it down to a 18′ S9 and attached it to the drain exhaust pipe at home, as changed to the Balun Design 4:1 unun, which does help with tuning on other bands. It also has 4 20M tuned radials.

The noise level is just way to high in Redondo Beach so I have been remoting into my rig at the whittier office, which has significantly less noise.  I still try it out from time to time, incase the band opens up.  I’ll probably use it as my vertical portable when I go camping, like how the Eagle One is setup.  I think this antenna works fairly well, but the city is a very noisy place for verticals.  You cant tell from the pictures, but there are about 20 High-Voltage powerline on 2 sides of this location, and 6 transforms within site of the roof, so that’s probably a big part of the issue.
