Model No: 6M7JHV
FEATURES:
The 6M7JHV is a mid-sized 7 element antenna designed originally for the late 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. Mechanical 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 1-1/2" boom breaks down into 5 ft sections for easy portability. An overhead guy sys-
tem provides additional boom support. It has become the standard of choice for HF/50 mHz DXpeditions.
