Hy-Gain VHB-246 Tri-Band Beam

Hy-Gain VHB-246 Tri-Band Beam

The Hy-Gain VHB-246 is a compact 6-meter and 144-148 MHz/420-450 MHz tri-band beam consisting of a 3-element 6-meter beam, and a separate interlaced 3-element 2-meter/5-element 70 
cm antenna. The 2-meter/70-cm antenna is mounted at right angles to the 6-meter beam. This permits the antenna to be oriented for optimum 6-meter SSB/CW operation, and optimum 2-
meter/70-cm FM operation. The VHB-246 is about the same size as a TV antenna, and can easily be turned by a lightweight rotator such as the Hy-Gain AR-35 or the digital AR-38. 

The VHB-246 utilizes a single 50-ohm coax feed for the 6-meter antenna, and a single 50-0hm coax feed to cover both the 2-meter and 70 cm bands. 

The VHB-246 is built-to-last – using 6063 T-6 aircraft strength aluminum tubing. And it assembles inless than an hour.
