So, you want a motorized or "screwdriver" style antenna for your vehicle? (the worst possible place to mount one). You could also go with a "stubby" screwdriver antenna and mount it up high, (my choice in the past).
All these antennas are great in there own way and have there place, but, let me offer you another choice, as if you need more choices! The TRX motorized antenna is not just a new antenna that looks like every other "screwdriver", This antenna is built to look great while it performs the way a good HF mobile antenna should. It is slender in design and has tight clearances to make it MUCH more attractive than ALL the others. The widest point of the antenna (the weather shield) is 1 1/2 in diameter. I know what your thinking, "I want a big 2" coil!
You need to consider that this is not the only factor in an antenna's efficiency. The placement of the coil is also a big factor. Our antenna has 26" of mast under the coil, this increases the efficiency compared to the short "stubby antennas. We use a 50 whip, this gives you coverage from 10 meters to way below the 80m band (under 3 mhz) if you want to use a shorter whip, you can, but on the lower bands the longer whip performs much better. Some of the short antennas give you 6 meters, that is possible with this antenna also with a shorter whip, but you lose out on the effectiveness of the antenna on say, 40 and 80 meters.
Stick with the longer whip. This antenna is built well! All the good antennas are CNC machined like ours, have quality gear motors just like ours, this is nothing new.
Our antenna uses poly carbonate for the weather shield. This is SUPER strong and wont crack or break, really!
EVERYTHING is stainless steel that has anything at all to do with structural integrity, the base, the mast, and all the hardware. You can also use this as a club if you get in a bind ; other parts are aircraft aluminum. That's just a fancy way of saying high quality stuff. This is super easy to mount.
You need a standard 3/8 x 24 antenna mount. Now, you want a good one! This is still much more antenna than a simple CB antenna. There are thousands of ways to mount antennas and just as many products, so I leave that to you. Please look at our antenna and picture this on your truck or car compared to all the others out there.
Everyone say's there's is the "best built and best looking" I will let you decide yourself. 1 1/2 OD at widest point. The coil is 1 and 1/16 inch wide (just over an inch) and 13.5 inches long.
(just 8 of the coil will get you to 80 meters, so there's plenty to spare). Total height with whip is 88" on 10 meters to 97" on 80 meters. 3/8 x 24 standard mounting.
Runs on 9 to 16 volts DC. Comes with 20' of cable and simple up/down remote control.
