The Original World  Famous K40

The original high quality, high performance antenna - the one everyone has heard of.

Long before we had Wilson antennas, this was THE antenna to have. It was certainly about in the 70's, when they were first made I don't know!  If something has been made the same for over 30 years it must be right!

Supplied complete with trunk (boot) mount, this can be dis-assembled to mount the antenna directly on the roof.

A special (very strong!) mag mount is available as an optional extra to fit on the antenna.

Total Length 1.6m
Coil length 50mm

K40 Mag Mount

Special magnetic mount for the K40 antenna.

Note that you must already have the trunk (boot) mount complete with cable which comes on the K40, because this simply sits (and is fastened) inside the mag base.

Very strong! 

K40 WeatherCap (white)

Available in WHITE only

A protective weather-cap to fit on your K40 mount to protect it when the antenna has been removed.

White plastic with a metal "quick release" fitting to fit on the K40 mount.

Unfortunately we have now sold out of the black version and only have these white ones.
