VHF is still the most common means to communicate on the water, especially offshore. But a radio’s effectiveness is dependent largely on the quality of its antenna. The Glomex RA1225HP 8ft Classic High-Performance VHF antenna is engineered for maximum long-range reception and transmission, it boasts a robust construction that ensures years of trouble-free service and is backed with a limited lifetime warranty.
The RA1225HP has a frequency range of 156/162 MHz with a gain average of 6dB. With a maximum input power of 100W and 50 ohms impedance, it’s vertically polarized to minimize signal reflection on water.
The internal elements of the collinear-phased antenna are made of spiral copper wires inserted into brass radiator tubes, which provide power, clarity and range.
Built to last, the double-thickness fiberglass tube has five layers of UV-resistant anti-yellowing paint and a rubber glue protection collar. The 1in ferrule is cast, electro-polished 316 stainless steel with an integrated feed-thru. With a DC ground, it comes with 20ft of RG-8X low loss twin screen coax cable with a pre-wired FME connector and PL-259 adaptor for simple connection. www.glomex.us
