Model No: 440-460-11HD
FEATURES:
The 440-460-11HD is a rugged antenna that has been computer optimized at the 440-460 MHz band. By raising the top
end of the frequency it allows use in the commercial band and now maintains good performance in the amateur band
even with 1/2” radial ice. The driven element has been engineered to handle up to 3 kW. It is ideal for repeater linking or
any point to point application. Clean patterns in most applications provide more reliable communications with less
inter-mode. An optional stacking harness is available when more than one antenna is required for reduced beamwidth or
additional gain. Users are surprised by the performance of this compact but potent antenna.
Construction is classic M2 for long term electrical and mechanical integrity. Elements are 3/8” 6063-T832 tube, mounted
through the boom on UV stabilized insulators and locked in place with stainless steel shaft retainers. The driven element
module is CNC machined and all openings are O-ring sealed. The driven element halves are aluminum brazed for a
perfect seal.
