The JAMPRO UHF Antenna has been designed for a low to medium

power solution, with a particular focus  on rooftop deployment.


The antenna is a vertically polarized (JVD) or circularly polarized (JCD) system enclosed by a full cylindrical radome for environmental protection and minimal urban visual impact.


The antenna is broadband over band IV allowing multiple UHF channels

to be transmitted at the same time.


Complete assembly, tuning and testing of your assembled antenna before

shipping ensures there is no question about its performance.


Directional antennas are a custom feature.  Call for details.
