details of the Hi-Q
The new NVIS/Combi antenna is
designed around the patented concept of the Hi-QHF antennas.
Two identical H-Q HF antennas
are mounted on a coupler box. This coupler box interfaces to the
feedline and the control connectors.
At a short distance above
ground, for instance on a ground mounted tripod or short pole the take
off angle in respect to the horizon will be high, hence NVIS
Hi-Q has gone a step further to
DX (long distance) communication of this antenna set up BY ADDING a
identical Hi-Q HF antenna. This third antenna is paced in a vertical
position, on a 90 degree angle in respect to the dipole. The verical
radiator can be tuned independently of the dipole.
The whole system now works as a vertical radiator with a tuned resonant
radial system. Consequently a lower radiation angle in respect to the
horizon is achieved, resulting in an improved long distance performance.
Deployment time needed for this system is less than 10 minutes. With
the use of a modern HF transmitter and advanced ARQ digital
communication protocols a total independent, light weight and high
performance portable communication system can be created.
