Antenna Switches

microHAM provides high power antenna switches for:

- single radio setups: micro SIX SWITCH, and micro TEN SWITCH

- two radios (SO2R) setups: micro DOUBLE SIX SWITCH, and micro DOUBLE TEN SWITCH

- multi radio setups: MATRIX SWITCH formed from micro FOUR + FOUR SWITCH, and individual N-way switches

- stacked antennas / power distribution: micro STACK SWITCH

microHAM do not provides manual controllers for antenna switches, instead we provide the most advanced automatic controllers for antenna switching available on the market.
Please check our Antenna Controllers page.

If antenna switch is situated outside the ham shack, it is necessary to use longer control cable.
It is better (although not necessary) to use a shielded cable, using the shielding as the GND return lead. When connecting micro DOUBLE SIX SWITCH, use two leads for GND, as it carries twice as many current. Don't forget to use a ferrite bead, as many turns as possible. Even one turn (cable directly through the bead) helps and filters out RF from the cable.

Determine the required cable cross-section (or diameter) from the following table, depending on its length:

Cable length [m] / [ft]	Conductor Diameter [mm]	Conductor Cross-section [mm²]	AWG
50 / 150	0.40	0.14	26
100 / 300	0.50	0.20	24
300 / 1000	0.80	0.50	20
