Hy-Gain TH-1 4-Band Rotatable Dipole
INTRODUCTION
The Hy-Gain TH-1 is a 26 foot 20-, 15-, 10-and 6-meter full legal limit rotatable dipole that is
inconspicuous and low profile, making it almost invisible from across the street. With its 13-foot
turning radius and 8-pound weight, it fits on even small roofs and is perfect for town houses,
apartments and condos - and can easily be turned by a lightweight TV rotator such as the HyGain
AR-35. If necessary, the TH-1 can even be mounted inside an attic!
And this antenna is no wimp! Its bidirectional pattern can help reduce QRM and/or noise while
maximizing your signal in the directions that you want -- so you can work some real DX. High
efficiency traps provide operation up to a full 1500 Watts SSB/CW on 20, 15, and 10 meters. Stub
matching is used on 6 meters for 1500 watt operation on this band as well.
The Hy-Gain TH-1 is built-to-last – using an incredibly strong solid rod fiberglass center insulator and
6063 T-6 aircraft strength aluminum tubing for the radiator. And it assembles in about an hour.
WARNING: Improper installation and assembly can be hazardous! Read these instructions
thoroughly before attempting to assemble, install or operate this product! High power
transmitting devices produce voltages that can cause severe burns or other injuries.
