Neat website.
I always thought that this would be a good qrp antenna.

Good mobile unit too.
But neither are for use in a moving vehicle.Quote:

Have you given any thought to moving the loading coil a bit higher up the mast - say, using an MO-2 or equivalent underneath it then incorporating a 3-4ft whip on top? The whips can be obtained as NOS surplus from Harbor Freight - they were OEM for a number of Chrysler products.
I don't normally sell my antennas. I help anyone interested in building their own. But if someone HAS to have me build one, the little ones are around $65 plus shipping depending on the cost of parts. The big ones I have sold for $105 plus shipping. I do it for fun. The main reason I am not doing it as a business is my wife's health has been bad for years and the cost here to obtain any kind of business licenses and the other REQUIRED stuff cost about $400 or more to start. I am happy just experimenting and helping others.
That big antenna in the snowy weather looks like the HARRP antenna outside Fairbanks. Is it?

My mistake. I was under the impression you were trying to drum up a small business.Quote:

I wrap my own coil around the PVC to make the small ones. I use about 40 feet of 18 Ga. uninsulated wire for that. I do that by stripping the covering off and then wrap the wire on the PVC as I strip it. I use a tuner no matter what just to "fine tune" the antenna to where I want to work. I went to the black PVC on the larger antenna because the sun just makes the white PVC too brittle.
I also have only a non COOLED or HEATED garage to do all this in. I love working in the garage in the winter but you can forget the summer when it gets to 100+ degrees out there. So then the antennna fun comes to a stop until it cools off. Usually that means from September ( maybe ) to May ( maybe ).

I do have a black antenna built and standing idle in the garage. I HAVE used one like it for mobile work but I tethered it so it would not wave around when driving. I used a HEAVY spring on it. I also have used the antenna with a 102" CB whip as a fixed antenna and it loaded up pretty good using my MFJ-945 tuner.

Those look like some "big guns" up there !!Quote:
