FEATURES
The 420-50-11 has been computer designed to cover the
entire amateur 70 CM band. It is ideal for 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 one dB
more gain and the pattern is much cleaner. Clean patterns in most
applications provide more reliable communications with less intermod.
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 find it 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 O-ring sealed. Internal connections are encapsulated in a
space-age silicone gel with nearly 4 times the dielectric strength
of air. Balun connectors are triple-sealed to the coax.
