Tuners can cost from about $ 350.00 to over $ 500.00 [ no antenna included ] , greater cost than most screwdriver antennas. Most screwdriver antennas will handle 400 to 500 watts [ enough for most mobile applications ] and all can be modified or custom built to handle 1000 to 1500 watts for base/mobile applications Antenna Systems; Antennas; Mobile Antennas; Screwdriver Antennas; Screwdriver Antennas.

They say that the best mobile antenna compromise (for HF) is a base loaded antenna, and the best of them is the screwdriver. they even have instructions on how to build one. The article drones on for all the myths of mobile antennas but never gives the reader a heads up on what is the best compromise out there The short version: any band below 10 meters requires an antenna too long to mount on a vehicle. This means that mobile hf antennas all operate at negative gain, with worse performance the lower the band. The best you can hope for is about 9-10% efficiency on 40m (100w in, 10w out) and that's with an antenna too large to take offroad To follow up on my previous video about antenna tuners, let me show you a useful antenna that I picked up months ago, but haven't had a chance to use.

  1. 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.

Other examples are the Super Antenna, the various mobile screwdriver antennas, mono-band Ham sticks, and ones like your link which is essentially a tappable ham stick. All of these are loaded ground plane quarter-wave verticals, so they will need ground radials added, even if it's just one as a tuned counterpoise For antennas mounted on vehicles and small watercraft, the metal body of the vehicle itself is most often connected to the station ground and used as a ground plane. Where insufficient space exists to accommodate a quarter-wavelength or larger antenna (typically an issue for HF or mediumwave antennas in mobile operation), antenna loading coils.

Back in 1991 there was a design for an HF mobile screwdriver antenna created by D.K. Johnsson, W6AAQ. It used a motor/gear assembly from a small electric screwdriver, some PVC, wire and pipe to form an antenna. This was called the Big DK3 antenna. This project is a modernized version of the Big DK3 using some 3D printed parts I created based on the original drawings.

The usual screwdriver matching box is a 4:1 transformer that matches the low impedance of the screwdriver to 50 ohms. The problem comes in when you mount it on a real good ground plane (i.e. that metal roof). It's physically short, so the radiation resistance is quite low. The inductor tunes out the capacitive component, but doesn't act as a. HF Antenna: Initially I considered a big-coil, adjustable load (or screwdriver) HF antenna that would use some fancy circuitry and mechanisms to cover multiple bands with ease once properly installed. But, after considering the price of those big babies, the heavy-duty mounting hardware typically required, and the extra complexity added. If you have recently installed an HF rig in your mobile along with an antenna or are planning to, it is important that you realize that the antenna is only one half of a dipole, and in the case of a mobile antenna the missing half is the vehicle and its capacitance to the ground under the vehicle MFJ Super Loop Antennas MFJ ScrewDriver Antennas Quicksilver Radio Products MinuteMan™ HF Portable Antennas Stealth Antennas -- HF Mobile Antennas By VE7BOC Texas BugCatcher - GLA Antennas Texas Twister - GLA Antennas Ventennas-- The Forbes Group Ventanna HFP-2 10 Foot HF Antenna-- 6.5 to 30 MHz !!!
