MK-76 A$49 The worlds smallest external aerial? Extremely small (about the size of a ten cent coin!), high gain, rugged, extremely low power (12ma) and low cost. Click here to see full spec sheet. Comes with either a BNC (eg 45XL, GPS II+), right angle MCX (eg 12XL) or SMB (Magellan). Maximum cable length is 3m, NOT normally enough to go from a bullbar to a dashboard on a 4WD.
