Description
Features: This heavy-duty VHF dipole array series is ideal for highly ruggedized, highly populated radio sites requiring wide-area omnidirectional coverage. The compressed boom design offers gain of 2 x 3dBd exhibiting a VSWR of <1.5:1 across the 155-174MHz band, whilst the design utilizes a smaller effective Stainless dipoles fixed to a heavy-duty aluminum boom, also offers a trade-off between strength and weight where critical, with the single boom design having the added benefit of being able to stack a further 3dBd receive array on top. The internal phasing harness is PTFE based low PIM-rated cable capable of input power levels up to 750 watts continuous, making this ideal for high power multiple transmitter applications. The cable harness assembly is fully enclosed within the antenna to remove any potential bird attack on the cable. • Compact height, high strength •Designed for sites with extreme ruggedized capability requirements snow and ice • Operate over entire 155-174 MHz VHF band without tuning • Low PIM performance • DC grounded • All connections are DIN
