PORTABLE Alpha Portable Antenna for 6-80 Meters.
The 6-80 Meter Alpha Vertical deploys in 60 seconds and is weatherproof. This system comes with a Field Bag, Tripod, Mast, 13 foot aluminum Mil-Stick whip constructed from 6 26 inch aluminum sections, Tripod Adapter, and Alpha Match. The system achieves an SWR of less than 2.5:1 on 10, 12, 15, 20, 30, & 40 meters. A broad band tuner can be used to achieve a perfect SWR match of 1:1 on all frequencies/bands above 80 Meters. Please remember to ground your rig and antenna tuner for optimum results.

NOTES ON USING THE Alpha Antenna AS A TEMPORARY OUTDOOR ANTENNA:
If you are going to use the Vertical as a temporary Outdoor Antenna, we recommend that you also purchase the optionally available Top of Mast Mount plus the 3 Element Counterpoise Kit and place it on your own support pipe (up to 1 1/4 O.D. inch mast).
To maintain the portable Alpha Antenna for temporary outdoor installations, you should be aware of three points that require periodic maintenance and inspection. They are: 1) Inspect the shock cord every six months for any deterioration and replace at least annually, 2) Place a 3 inch length of heat shrink around the hex nut at the base of the MilStick whip to keep the set screw in place and inspect/replace the heat shrink when you do the shock cord, & 3) Place a bit of silicone around the top bolt on the Alpha Match and inspect/replace when you do the shock cord.
It is also a good idea to take the MilStick whip off of the Alpha Match when it is not in use, because as with any antenna system, wind shearing can cause an element to break at connection points. The connection point on the MilStick whip is where the first vertical section inserts into the ferrule. Also please note that leaving the MilStick whip on the Alpha Match increases the chances of the top bolt developing a slight tilt, although a slight tilt of the MilStick whip will not affect the operation of the antenna.
