The 80M3L Yagi is a computer refined and improved performer, both mechanically and electrically. A low loss hairpin match provides perfect 1:1 match capability. Element halves start with 3” o.d. 1/8” wall tubing and taper through 2” sleeved, 1-3/4”, 1-1/2”, 1-1/4”, 1”, 3/4”, 1//2” &3/8” tips. The 3” and 2” sections are joined by a custom fiberglass insulator to section each element half for the linear loading (3/8 alum. tube). A solid 2” O.D. Fiberglass rod, sleeved to fit inside the 3” elements, serves as the center insulator for each element. The center boom section is 4-1/2" O.D. x 20' with nearly 1/4" wall thickness. The two outer boom sections are 4" O.D. x 20' x 1/8” wall.
The new, highly efficient 3/8” tube linear loading terminates above the boom and out of the element plane to reduce inductive cancellation, provide element support, and reduce excessive droop. The new, heavy duty 1:1, 5 KW balun , now housed inside the phone / cw switch enclosure provides plenty of power handling margin. The standard phone / CW band switching relays and high Q (over 600) coils are housed in a fiberglass housing. The whole assembly is now field serviceable and small frequency adjustments can be made in the CW part of the band. On the air, you’ll find little or no competition for the 80M3L. Upgrade parts are available for older 80M3’s.
