The KP Performance KP-138SPOMA-8-NF 134 to 174 MHz, 4.5 dBi omnidirectional antenna, with N female connector is a low cost, high performance antenna designed for high power applications. With a frequency range of 134 to 174 MHz, this omnidirectional antenna is suitable for military communications, trunking, public safety, industrial communication, and amateur radio applications. This high gain 4.5 dBi antenna transmits high power signals, increasing the signal strength, thus providing improved coverage, better broadcast control, and faster speed.

KP's KP-138SPOMA-8-NF omnidirectional antenna is made of fiberglass, is omnidirectional and covers good bandwidth and range. It has a 1.5 VSWR that results in the best power transfer and reduced losses. This 134 to 174 MHz VHF/UHF antenna radiates equal power in all directions perpendicular to the axis, with power declining to zero on the axis, when graphed, radiation pattern describes a doughnut shape. It comes with a N female connector, which is a threaded and weatherproof that ensures a reliable physical connection.

This omnidirectional antenna uses vertical polarization to transmit signals, thus reducing interference and performing better at lower heights. Our omnidirectional antenna has 1 port to connect an external circuit with 100W maximum input power per port. All components of this 4.5 dBi antenna are DC grounded for lightning protection, have a rugged outdoor design, and have a high-power handling capacity.

This antenna with a 4.5 dBi maximum gain is ideal for LMR, military, airports, construction, mining, commercial applications and radio users. This KP-138SPOMA-8-NF omnidirectional antenna from KP comes in compact packaging for lower shipping costs, is in stock and available for same-day shipping.
