You could start selling those as kits
I copied a guy that used to manufacture them. His name is Jerry, KR7KZ, it's his design. QST even ran an article on them a while back. He gave me the plans to build them. He doesn't make them anymore.

You still 'sperimenting with antennae?! :rocker:
LOL, the Jpole has served me well for 5 years, I think I might retire it next year and go to a higher gain dual band NMO style 5/8 whip. I have it mounted on a Bandi mount now, it has been there for a couple of years. When I first had it on the truck I had it up on the roof rack. It was just too tall up there, it hit everything.. even a low power line at my 'rent's house.. eeek..

I have made a bunch of these Jpoles. Truckers love them. I guess they work very well with their fiberglass cabs. I know of 2 UPS drivers that have had them on there trucks, for years and years..

I'm currently building a 1986 Yota single cab truck. My Brother in law has a 85 Yota single cab truck as well.. we have been using this radio http://www.amazon.com/LEIXEN-VV-898-136-174-400-470MHz-Transceiver/dp/B00LS8AJRW/ref=sr_1_2?ie=UTF8&qid=1418141191&sr=8-2&keywords=mobile+dual+band along with a bunch of these radios http://www.amazon.com/BAOFENG-BF-888S-Transceiver-Illumination-Flashlight/dp/B007F7MZ04/ref=sr_1_1?ie=UTF8&qid=1418141228&sr=8-1&keywords=bf888s&pebp=1418141229920 for trail communications... they work FANTASTIC!

I have been meaning to get these pics posted for a couple of weeks, and life has just gotten in the way too much lately.

I recently acquired a 2013 FJ and immediately got to work putting together the mobile station. The antenna is a homebrew screwdriver that I built about fifteen years ago that I ran on my old 94 Suburban until the purchase of the FJ.
It has proven to be an admirable performer and has held up well to a significant number of miles and QSOs.

I decided to use the ladder as the attachment point, requiring the construction of custom mounting blocks. Thankfully, I have the good fortune of being a machinist and having a my own equipment, just for such projects. The mounting blocks were made from aluminum bar stock. The antenna bracket is the original bracket that I made when I built the antenna.

Mounting the radio and RigRunner

mounting the control head for the radio required a bit more machine work, but this time out of a block of nylon that I had laying around.

The block is made to fit the coin tray located just behind the gear shift (MT), and is held in place by 3M adhesive backed velcro.

At the time that these pics were taken, there was still a bit of cleanup to do in the form of cutting power and control cables to length and getting everything plugged in and mounting the control box for the screwdriver antenna.

I still need to get a 2m/70cm antenna mount made, but that will have to wait until I get some other projects completed.

I run a Kenwood TM-D710A and a Yaesu FT857D, with a Diamond 2m/440 retractable antenna and a Yaesu ATAS-120A auto-tuning HF antenna. The radios are hooked up to a Panasonic Toughbook for APRS mapping / messaging and HF logging...along with with a Clearspeech DSP speaker and various other related items....
