A very popular complete mag mount antenna. Basically the same as the Sirio ML145 but £10 cheaper!!
Not quite as good quality as the original Sirio version, but at £14 less it offers good value for money and should work just as well.
This is very similar to the old Avanti Moonraker (remember them from the 70's?).
The antenna is a SO239 fitting and is supplied complete with a magnetic mount. The mag mount is enclosed in plastic (stops it rusting) and comes complete with a rubber boot (helps stop it scratching).
