Turning radius 46' Mast Size 2 in. nom. or specify Wind Area / Survival 19 sq. ft. / 100 mph Weight / Ship wt. 200 lbs / 250 lbs -Truck Price $ 2,600.00 FEATURES The 80M2 is a real performer, both mechanically and electrically. Element halves start with 3" diameter tubing and taper through 2", 1-3/4", 1-1/2", 1-1/4", and 1" sections to the 3/4" tips. The 3" and 2" sections are separated by a polyethylene insulator to allow for the linear loading (#10 copperweld). A solid 2" O.D. Fiberglass rod, sleeved to the 3" elements, serves as the center insulator. The linear loading terminates above the boom and out of the element plane to reduce inductive cancellation, provide element support, and minimize excessive element droop. In fact, the 80M2 looks better than some 40 meter models. The 1:1 balun and phone / CW power switching relays are housed in heavy wall ABS cannisters at the center of each element. Relay requires 12 VDC supply. On the air, you'll find little competition for the 80M2. 7560 N. Del Mar Ave, Fresno CA 93711 (209) 432-8873 FAX (209) 432-3059
