144-174 MHz Base-Loaded Antenna

The Pulse Larsen OM150CK is a 2.5 dB gain antenna covering 144-174 MHz for mobile two-way radio use. Its base-loaded design operates without a ground plane, simplifying installation on vehicles where a metal roof is unavailable. The stainless-steel whip extends 49 in and handles up to 200 W. This unit suits fleets and hobbyists needing reliable VHF coverage.

Verify Mounting Surface And Cable Routing

Confirm the adhesive mount will bond securely to your chosen panel; clean, flat surfaces provide the best hold. Ensure the 17 ft RG-58 coaxial cable can reach your radio without sharp bends or pinch points. The factory-fitted PL259 connector mates with standard UHF female sockets, so check your transceiver port matches before ordering.

Stainless Whip And Factory-Terminated Coax

The silver stainless-steel whip resists corrosion and road vibration during daily driving. A 2.25 in diameter coil base houses the matching network and provides a stable adhesive footprint. The RG-58 cable is permanently connected to the coil and terminated with a PL259 plug, eliminating field soldering and reducing potential failure points at the feed point.

Questions about this item

Does the 17 ft RG-58 cable come with the PL259 connector already fitted, or must I crimp it myself?

The 17 ft RG-58 cable is supplied with the PL259 connector already attached to the coil, so no crimping is required.

The gain is shown as 2.5 dB and 2 dBi — which figure should I use when comparing this antenna with others?

Use the 2 dBi figure for direct comparisons, as dBi references an isotropic radiator while the 2.5 dB value uses a different reference.

With a 200 W maximum power rating, will the antenna handle a typical 50 W mobile transceiver without overheating?

Yes, the 200 W rating provides ample margin for a 50 W transmitter, so the antenna will operate well within its limits.
