Introducing the COMPROD VHF Folded Dipole Antenna Line
Covering VHF Low Band Aviation and High Band VHF- Built Durable for Industrial Use
Timberline Radio Systems Introduces the Comprod 870 Series Antenna Product Line.
Considered the Pioneer of Radio Antennas, Comprod Communications has been manufacturing antennas nearly, since the invention of radio. Their product lines include Folded Dipoles, Verticals and Cross-Polarity as well as a wide selection of duplexers and multiplexers. Comprod meets and exceeds the worlds finest RF standards.
Our featured product is the Comprod 871F 1/2 wave single lobe antenna better known for it's practical deployment especially in general class and portable applications.
The Comprod series is unique in its high efficiency and exceptionally wide bandwidth, covering the frequency ranges of 118-137 or 138-174 MHz at a VSWR of 1.5:1 or better. As a result of genuine, wide bandwidth design, the Comprod series is perfectly suited for multiplexed and multi-channel systems.
Several model variants of this rugged antenna are available: Pattern adjustable version with external cable harness enabling its pattern to be changed in the field; and the fixed pattern versions (such as the 1/2 and 1/4 wave options), that includes the cable harness inside the mast and dipole booms.
