420-450-11HP, 420-450 MHz

The 420-450-11HP is the high powered version of the standard model 420-450-11. The driven element has been engineered to handle up to 3 kW PEP. Computer optimization has allowed the antenna to cover the entire amateur 70CM band. It is ideal for the repeater linking or any point to point application. Comparing it to a common reference, the KLM 420-450-11, it has the same usable bandwidth with a full on dB more gain and the pattern is much cleaner. Clean patterns in most applications provide more reliable communications with less inter-mod. An optional stacking harness is available when more than one antenna is required for reduced beamwidth or additional gain. Because the antenna covers the whole band, many users fit it as a natural for ATV and general repeater use. 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 3/16" 6061-T6 rod, 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 connectors are O-ring sealed. Internal connections are encapsulated in a space-age silicone gel.
