The TX38 triband Yagi has now been selected as the official antenna of the WRTC-2014 competition.
The TX38 is a 30 pound Yagi antenna with 8 full-sized elements (2 elements each on 20 and 15 meters and 4 elements on 10 meters). It features mono-band performance across the three major HF frequencies while utilizing a single 50 ohm feedpoint. A high quality 1:1 balun is included with this antenna. The TX38 was designed for wide bandwidth across 20, 15, and 10 meters and is rated to survive more than 80 MPH winds on a 14.5 foot (4.4m) boom. The antenna features all stainless steel element hardware and element mounting blocks to reduce wind vibration in the elements. NEC 4 with custom optimization software developed specifically for multi-band, interlaced designs was used to design the TX38. Real world verification have shown the TX38 to have superb gain, VSWR, and front/rear across the 10, 15, and 20 meter frequencies. This antenna is ideal for DXpeditions, field day, or permanent installations.
The TX38 is MADE in the U.S.A.

It is an honor for Cycle-24's TX38 antenna to be selected as the official yagi for WRTC-2014. We sought to deliver a new and exciting antenna design that would be fitting for this unprecedented international contesting event to take place in New England in 2014. The TX38 was electrically and mechanically designed to the exacting standards of the WRTC committee. Scott McClements, WU2X, wrote custom optimization software specifically for the design of multiple-band antennas. His electrical design provides superior performance across the 20, 15, and 10 meter bands.
