PORTABLE Alpha Portable Antenna for 6-80 Meters.
The 6-80 Meter Alpha Vertical is a balanced antenna that is weatherproof. This system comes with a Field Bag, Tripod, Mast, 13 foot aluminum Mil-Stick whip, Tripod Adapter, and solid state Alpha Match. The balanced system includes components that are deployed at the proper heights for optimum 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 other frequencies/bands above 80 Meters. Please remember to ground you rig and antenna tuner for optimum results.

OPTIONAL 3 ELEMENT COUNTERPOISE KIT: The optional "Counterpoise Kit" is will enhance performance of the antenna by providing an enhanced ground plain, which in most basic terms will put more of your radiated signal into the air by reflecting your signal skywards rather than allowing it to permiate the ground around the antenna. Additionally, adding the "Counterpoise Kit" enhances 40 & 80 meters, because the lower bands tend to lend their performance to the NVIS properties of an antenna system. By adding horizontal Counterpoise elements that are close to the ground, NVIS performance for 40 and 80 meters is enhanced. The Counterpoise Kit also serves to guy the antenna system for increased stabilization in light to moderate winds.
OPTIONAL NVIS KIT: An optional "NVIS Kit" is, which will enhance performance on all HF frequencies and enables increased NVIS on the bands that very much depend on horizontally positioned active elements (40 & 80 meters).
ALPHA MOTO CONVERSION KIT: The optional "Alpha MOTO Conversion Kit" enables the Vertical Antenna to be become a 6-40 meter mobile antenna in less than 60 seconds.
Included with your Alpha Vertical is the durable 13 foot aluminum MilStick whip that shock cords down to 26 inches in length. Also included is a tripod that stands approximately 6'6" high. This tripod is designed to be your counterpoise system, to which you can add the optional "Counterpoise Kit" and or the "NVIS Kit" for even greater performance. The tripod includes a Mast Adapter where the Alpha Match will mount. Your coax attaches to a UHF SO239 connector on the Alpha Match.
The differences between the Alpha EzMilitary and the Alpha Vertical antennas are:
EzMilitary comes with a MilStick whip that breaks down into 12 separate 13 inch sections with shock cord.
Vertical comes with a MilStick whip that breaks down into 6 separate 26 inch sections with shock cord.
EzMilitary comes in a 16 inch bag.
Vertical comes in a 26 inch bag.
EzMilitary comes with a Jaw Mount.
Vertical comes with a Tripod and Mast Adapter.
EzMilitary comes with one Counterpoise wire.
The Vertical uses the Tripod as a Counterpoise.
NOTES ON USING THE Alpha Antenna AS A PERMANENT OUTDOOR ANTENNA:
If you are going to use the Vertical as a Permanent 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). Many people use their Alpha Antenna as a permanent Station Antenna installation, even though it is not the recommended use as this is a portable antenna. As with any permanent outdoor antenna installation, the Alpha Match and other components comes with its own set of preventative maintenance requirements and unique set if risks.
To maintain the portable Alpha Antenna for permanent outdoor installations, you should be aware of four 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, and 4) Inspect the top and bottom bolt to ensure that the nut is tight (Note - Do not ever loosen the nut and only turn the nut to the right to tighten it if your top element has a tilt or either nut becomes loose.)
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.
