    Hello, I was looking into putting a mobile HF in my company car, I was at a Radio store and the saleman told me that it would be a 8 or 9 foot antenna. That probably would not look good on my company car, are there any other choices. I like to operate 40 meters and I practically live in my car traveling. Any ideas is appreciated..

    Alan has lots of Mobile info ... you don't want a mag mount to start with.

    Small antennas = HORRIBLE performance. I run the Icom IC-7000 with the AH-4 autotuner feeding a Hustler mobile antenna. I can operate on any band from 40 through 6 using a 20 meter resonator -- and use the 40m resonator only when I am operating "mostly" on 40. The "Backpacker" antenna or a "Hamstick" would also work -- but not nearly as well.

    In my case, the radio and the tuner are in the trunk, on a COMMON ground.

    My suggestion is to get a Hustler, cut and screw together the mast so that you can fit it in the trunk (unless you have a trunk that will take a 4 foot mast, when folded), and use a low-profile 3/8-24 mount. You MUST have a good ground.

    The AH-4 is a TRUE Antenna Tuner. (In other words, it MATCHES the ANTENNA to the feedline -- instead of "flattening" the network of feedline + antenna.) Any "tuner" that is inside a radio is NOT a tuner -- it is truly a "line flattener", and is highly inefficient.

    I've used the Hustler with three resonators ( 40, 20, 15) and it seemed to work as well as any other mobile antenna.

    check out HI Q. The HI Q antennas are similar to screw driver antennas but better than most and, of course
    a bit spendy. I dont think you can find a better mobile/multi band antenna. No tuner/coupler required.

    My husband "K9ILL" runs a Wilson (FGT-2) 11 meter antenna on his 18 wheeler with a 1.1.1 swr on 20 meters and with a tuner, also works 15 and 17 meters. The Wilson FGT-2 is only 2 feet tall and comes with a 3 inch whip. Remove the 3 inch whip and replace it with a 40 inch whip and prune it down to resonance on 20 meters. You should wind up with about a 34 to 37 inch whip to get 1.1.1 swr on 20 meters. You'll wind up with about a 5' antenna and talk nationwide. 73...KD9CFJ

    I use a modified cb antenna as well. A company called Truck Spec markets one called Terminatior II. Its ugly but a remarkably good antenna. Has great broad band characteristics and by changing whip length you can change bands. For instance, I added a 60 inch whip and moved it to 15 meters. With a tuner, I also use it on 20. It retains its broadbandedness (is that a word?) over the entire general phone segment on both bands. Now I basically use the tuner as an antenna switch. Contacts have been made world wide on 20 and 15. I have another one mounted on the other side for 10 meters. They work well.
