The Andrew AVA7-50 1-5/8″ Foam Heliax 50 ohm coax cable is a low loss, high power corrugated RF transmission line for transmitter-to-antenna and combiner runs in professional broadcast and communications systems.
$ 30.43
The Andrew AVA7-50 1-5/8″ Foam Heliax 50 ohm coax cable is a high power, low loss transmission line designed for demanding RF applications in broadcast and communications plants. Its corrugated outer conductor and foam dielectric construction provide excellent attenuation performance and power handling, making it suitable for main feeder and combiner-to-antenna runs where reliability and long-term stability are critical.
The AVA7-50 cable is intended to be terminated with compatible 1-5/8″ Heliax connectors, supporting straight, right-angle and bulkhead styles to suit different rack and tower configurations. Its 50 ohm characteristic impedance and construction are matched to modern transmitters, combiners and filters, allowing efficient transfer of RF power along the full length of the feeder. In a typical broadcast installation it forms part of the main RF path between the transmitter output and antenna systems within your wider transmission infrastructure.
In daily use the Andrew AVA7-50 delivers consistent low-loss performance that helps preserve system efficiency and keep transmitter headroom within specification. The corrugated construction offers a practical balance between rigidity and bend capability, simplifying routing through cable trays, wall penetrations and tower climbs when installed according to manufacturer guidelines. For broadcasters and RF engineers standardising on high quality transmission line, AVA7-50 is typically combined with dedicated Andrew cable accessories such as hangers, grounding kits and weatherproofing solutions to build robust, long-lived feeder systems.
