Introducing the Amazing Tune-A-Tenna!! (patent #7286100)
WHAT’S SO AMAZING?
World's only remotely adjustable 1/2 wavelength dipole antenna...A small light weight, easily transportable, high frequency antenna that:
1. Is truly resonant from 1.8 MHz continuous to 55 MHz.
2. 1.5 to 1 or less SWR
3. 1.5 KW Power Rating +++
4. No Tuner required
5. Efficiently radiates all Transmitter power output
6. Effective Radiation = Effective Communications
7. Less chance of damage to the transmitter due to high SWR and heat
build up in the transmitter.
8. Prevents SWR fold back circuits from engaging and automatically lowering power output.
HOW IT WORKS
Tune-A-Tenna works by extending or retracting the 2 antenna elements until you have
reached the point of resonance for the desired operating frequency,
thereby providing maximum forward R.F. power and little if any
reflected R.F. power.
We have effectively built a custom cut-to-frequency dipole antenna
each and every time you change frequency without leaving the
equipment operating position.
This antenna can be controlled by the flip of a switch or could possibly be controlled by the
micro processor in most modern day transceivers. This would allow the antenna to track the VFO while receiving. You would
instantly be at the correct length when the -5- transmitter is keyed.
Doubly insulated from the support structure for maximum safety from lightning, EMP's, etc.
A simple electro-mechanical design, only 2 diodes, 2 unit switches and +13.8 UDC electric motor that allows the Tune-A-Tenna to be operated from a battery during power failures.

The final manufactured version will be much smaller and lighter. Quality materials are used throughout; all RF parts are stainless steel. Built to stand the test of time.
