PLAN1018 - CIRCULAR POLARIZED ANTENNA

This unique antenna design makes use of a special technique developed by the broadcast industry. The antenna makes the radiated wave ROTATE as it leaves the antenna. This means that on CB frequencies the signal will rotate about 27,000,000 times per second. It actually "screws" itself into space. In this way, the wave is continuously changing from vertical to horizontal polarization and every angle in between. It's the best of both worlds. Get improved performance on skip signals, mobile signals, other base station signals. The antenna is easily constructed with low cost materials. Construction plans give all dimensions and construction steps for CB antennas as well as 6 and 2 meter amateur radio antennas.

PLAN1020 - INVERTED "V" ANTENNA

This highly effective CB antenna design can be incorporated into the guy wires of a TV antenna for cost reduction. All that is needed (in addition to the guy wire) are several "egg" insulators and a length of coax. Not only easy construction and tune up, but you also get about a 5 dB power gain over regular antennas. Makes a perfect "disguised" CB antenna.

PLAN1020 - Inverted "V" Antenna .................. $12.95

PLAN1021 - MOBILE LOW PROFILE ANTENNA

Most mobile antennas have several disadvantages against them. Conventional antennas tend to pick up and create electrical noises. Ignition system noise and static charge build-up can cause overpowering noises in a mobile radio. This low profile 26" ring antenna mounts just 3" above the car roof. It contains both vertical and horizontal polarization characteristics. Radiates well in all directions. Very low cost and easy to construct and tune. Will reduce normal noise of 5-5 to as low as 5-1.
