Diamond HF-10FX 10m Mobile Antenna 28MHz, 250W SSB, 1/4 Wave Base Loading, Flexible Fibreglass

The Diamond HF-10FX is a compact, lightweight 10-metre (28 MHz) mobile antenna featuring a base-loading coil and a flexible fibreglass radiator — making it an ideal choice for vehicle-mounted HF operation on the 10m amateur radio band.

With 250W SSB power handling, a VSWR of less than 1.5:1, and a PL-259 plug for direct connection to a standard mobile mount, it's a straightforward, reliable 10m mobile antenna at just 1.1m tall and 180g. Compatible with standard 3/8"x24 mobile antenna mounts and magnetic bases.
