HFpack is an international news organization covering amateur radio High Frequency portable and mobile communications These have an optional screwdriver antenna that covers 40 m thru 70 cm. How efficient the Yaesu screwdriver is, is debatable whereas using a Scorpion screwdriver antenna is much better or even a Tarheel screwdriver antenna for the HF Band. Do your research on both screwdriver antennas before purchasing either one

An HF antenna needs some ground plane right under it and when you pull the antenna feedpoint away from the ground plane as in mounting it to a roll bar or trailer hitch, it raises the impedance and introduces ground loss. So a good shortened coil loaded HF antenna will have a much lower impedance than 50 ohms, could be down at 10 ohms on 80m or. Most HF mobile antennas are already length-compromised and shortening them isn't really a viable option if you're seeking good performance. You could use a cap hat (capacity hat) which will allow you to shorten the antenna and maintain some level of efficiency, but you have the extra wind load and complexity to contend with IC-7300.

High-frequency mobile antennas are not perfect performers, regardless of their owner's DX claims. For example, if you were to mount a 1/4 wave, 10 meter resonant antenna (8.2 feet long), made of solid silver rod, in the middle of the roof of an average vehicle, the efficiency would barely meet 90%. In the real world, it is more like 80% Bushcomm HF Antenna Systems Australia. Manufacture & Worldwide Sales of Commercial & Military grade base station, portable & mobile aerials. Specializing in Broadband HF/VHF Antennas & Masts/Tower I might mention that HF mobile antennas have changed a lot in 10 years.

Very popular today, and almost nonexistent 10 years ago, are a variety of motorized screwdriver antennas which use a single whip with a motor-driven adjustable inductor to. Mobile applications set the focus for the initial requirements in the design of the Scorpion Antennas. Mobile operators need an antenna that will perform in all the different orientations a vehicle may operate, the highly interactive variable RF environment, and of course survive those bird strikes

Comet UHV-6 Mobile Antenna

I decided to build a basic screwdriver antenna for the mobile, patterned after the original DK3 introduced by Don Johnson, W6AAQ back in 1991. This is a multiband antenna which is tuned by a gear-head motor, ultimately refined to operate from the internal workins' of a common powered screwdriver - Hence the name While the antenna in the diagram above will function well, it would be much better if you used a 1:1 balun in place of the center insulator, like the COMTEK Jerry Sevick W2FMI Series Current Balun COM-BAL-11150T.
