ProMaster HF antenna
Built for the harshest military and civilian environments, the Alpha ProMaster is a 43 foot tuner free 10-80 meter 500 Watt base & transportable antenna. Perfect for all HF modes including, but not limited to, CW, SSB (USB/LSB), AM, etc.
The 43 foot element is composed of an 18 foot vertical and a 25 foot horizontal element, which are stealthy and provide simultaneous Vertical DX & Horizontal NVIS take-off angles for your radiated signal. Simply install the antenna approximately 5 to 7 feet off the ground on any conductive or non-conductive mast and connect your coax to the SO239 on the Alpha Match. Then the Vertical element will enhance high band DX while the NVIS Element enhances low band NVIS. The included RF Ground wire and stake then complete the circuit at the antenna (Note - Without the ground there would be no return path for current, which means that there would be an open circuit and the system would not work as efficiently).

Optional Expedition Bag:
This base antenna is also easy to take on portable expeditions, where you'll enjoy the approximate 5 minute setup/take-down for deployment. When kept in the optional Expedition bag, the vertical element and all accompanying hardware stores away at less than 3 foot 3 inches.
The optionally available heavy duty steel tripod is designed for at least 2 years of continuous outdoor use, in non-salt water environments. Our two year outdoor test of this tripod revealed that it was still structurally sound, and only showed signs of fading with some surface rust (mainly on/around the screws).
