Antenna KUM480 with mounting

KUM480/KUM481

The 4.8m (16’) HF/SSB antenna balances length with performance. A 2-section construction.

The KUM480 is for mast mounting, and the KUM481 for mounting directly on 1”-14 threaded mounts.

KUM480-1 

With connection box for use when using coaxial cable.

KUM480-2 

With connection transformer box for receiving purpose only.

The transformer is recommended if the antenna is used at low frequencies (0.15-30MHz) or when long cable feeding is necessary.

KUM481 can also be delivered with connection box or connection transformer box on request.

Mounting hardware available as option:

For mast mounting: N070F, N075F, N080F, N085F and N090F (see page 26 for details)

Note: Two clamps required for each antenna.

For KUM481 a N200F upper support is required.
