RFI VHF Helical Roof Mount 1/4 Wave Antenna 156-165 MHz

RFI VHF Helical Roof Mount 1/4 Wave Antenna 156-165 MHz

This is a range of flexible, helically loaded electrical 1/4 wave antennas for applications where height restrictions prohibit the use of standard quarter-wave antenna. Fitted to a standard MB9 antenna base, the HPM-RM Series is less than 440mm tall. The lower section of the antenna is a molded former while the upper section is a helically wound stainless steel section providing a flexible antenna suitable for height restricted areas. The antenna is ideal in mining applications because of this flexibility. The antenna is supplied factory tuned to cover 156 to 165 MHz at a VSWR of less than 1.5:1.
