They are smaller and lighter than the mobile versions The Hustler radio base antenna is a high performing antenna that can be mounted on the ground or the roof based on preferences. It is flexible and serves the purpose perfectly. Below are the reasons why it is top-rated at the moment: It covers 10, 15, 20, 40, and 75/80 meter bands with ease for not just transmitting but also receiving the signal Established in 2008, Chameleon Antenna has been a great source of enjoyment for amateur radio operators. Their antenna designs have inspired other companies to also rethink their own antenna systems. Chameleon Antenna is proudly manufacturing antennas that are 100% made in the USA

Mobile antenna tri-band 6m 2m 70cm Comet SBB-15 . Comet SBB-15 original guaranteed mobile antenna, tri-band 50/144/430MHz, with a gain of 2.15dBi on 6m, 4.5dBi on 2m and 7.2dBi on 70cm and a length of 1.53m.Type: 1/4 wave 50Mhz, 6/8 144MHz, 3x 5/ A doublet antenna (dipole), cut for 80 meters, will not work on 40 meters because 7 MHz is an even harmonic multiple of 3.5 MHz. This means that if we try to feed 7 MHz to 3.5 MHz (80 meter) dipole, the 7 MHz current would be at a minimum (null) at the center feed point of the 80-meter dipole The mobile setup is an ICOM IC-7000 and LDG AT-7000 automatic antenna tuner (now superseded by the IT-100). The VHF/UHF mobile antenna is a Diamond MR77 for 2m / 440 MHz. The HF mobile antenna is a Hi-Q 3/80 screwdriver antenna with a 1 foot mast extension, a 4 lobe capacity hat, and a 4 foot whip from a 75 meter HamStick. I use an Ameritron. screwdrivers with large top hats are close to equal at the top of the. heap. Taking away the top hat costs about 2 dB. ~30-40% loss of power. Hustler and Outbacker are about 9 dB down from the top. ~85% loss. Hamstick is about 12 dB down from the top. ~95% loss. 11.5' whip is about 13 dB down from the top Contact Us.

Need some HF antenna advice what mobile HF antenna to get

The tuner in my K3 makes it useful from 12 through 30 meters. I also have a separate dipole for 10 meters, and a omni-type antenna for 6m, up in the attic. The all work reasonably well. You could also use a good mobile antenna like a screwdriver that is actually mounted in your back yard with radials. I've always wanted to try one of.

Make full use of your sunspot cycle with PATRIOT's low angle signal. Instead of typical traps, hy-gain's resonators are placed in. It is easy to build, construct and erect a dipole antenna for the HF bands: 160, 80, 40, 20, 15, 10 metres, etc using a few simple components at a minimal cost and get great results. Dipoles are one of the simplest antennas to build or construct and erect for the HF amateur radio bands, and on top of this they can be very effective. Dipoles are.

You simply are not going to find a mobile all band HF antenna that works decent and is 1.5 to 2 meters tall. If you can stand a little bigger than that I really like the Tarheel 100 and 300 models.
