Locate the small Coaxial feed Loop: Slide the clips that are attached to the small Coaxial Feed Loop onto the support pole. Locate the large Coaxial outer Loop element: Slide the clips that are attached to the large Coaxial Feed Loop onto the support pole. Replace the Rubber cap onto the top of the center support pole. Attach the PL259 connectors on the outer loop to the grey box: Attach the PL‐259 connectors on the larger Coaxial Loop Element to the SO‐239 connectors on the grey Alpha Match box. Attach your coax: Connect your PL259 to the T‐Connector on the small inner loop, and then run your coax to your equipment. Tuning: Start with MINIMUM power & select your frequency, then turn the black knob Optional 40‐80M on the grey Alpha Match till your rigs meter peaks with the loudest audible noise floor. Booster Cable The Booster cable Fine Tuning: Slide the inner/outer loop up or down the center support pole while enables 20W PEP SSB on monitoring for the lowest SWR on an inline SWR meter, your rigs SWR meter, or an 40/60/80M and installs in antenna analyzer, as you change the distance between the loops. Series with the 10‐40M outer loop. BEFORE increasing your power to 100W, please ensure your SWR is optimally tuned. Page 2...
