Mosley Electronics, Inc., announces the latest addition to the "rap-Master line of amateur radio antennas, the Classic 36, a six-element tri-band beam incorporating the famous Classic Feed System, "Balanced Capacitive Matching" (U.S. Patent No. 3419872). Classic 36, rated for maximum legal power on 10, 15 and 20 meters, features the Classic coax-fed balanced element for more efficient beam performance, increased bandwidth, and maximum gain. As a Mosley Trap^Master, CL-36 offers Trap-Master Traps and weather-proven construction, as well as automatic bandswitcbnng by means of high-impedance parallel resonant Trap Circuits.

CL-33 for 10, 15, and 20 meters

A new addition to the Trap-Master family of quality beams is the Classic 33 for 10, 15, and 20 meters with a power rating of 1 kW AM/CW and 2 kW PEP SSB. This new Mosley beam which incorporates the same durable, long-lasting Mosfey traps made famous by the TA-33 and other Mosley Trap-Miaster beams, features a new type of matching system developed by Mosely engineers — 'Broad Band Capacitive Matching' with coax fed balanced element. This new type of matching system not only brings the ham an antenna of greater efficiency, but a beam with a FULL 8 dB of gain over reference dipole on all three bands or 10.1 dB compared to isotropic source. Front-to-back is the maximum possible on all three bands. SWR is 1.5/1 or better.
