FEATURES:
The 6M7JHVHD is HEAVY DUTY version of the 7 element antenna designed originally for Dave Batcho, N5JHV. The
JHV's excellent gain is coupled with a very clean pattern for reducing local noise, making it ideal for long-haul terrestrial
and EME communications. An outstanding performer by itself, the JHV also produces 17 dBd in an 4-bay array. Mechan-
ical features include machined aluminum element-mounting blocks, O-ring sealed connectors and balun, silicone-gel
sealed T- match block, and stainless steel hardware. Elements are 3/8 tube and DC grounded. The 2" boom come in 95
in. sections for UPS but now strong enough to handle 100 mph winds or heavy ice load. An overhead guy system pro-
vides additional boom support.
