Hi all,
I need another antenna for my Garmin128 GPS for mysecond boat. I want
to build a blade antenna using a MMIC. I've lost the design specs for
the antenna. Anyone know how to calculate the size of the "blade"

Its a pain in the a** buy one.
Without the phantom powered preamp you loose to many SAT's after coax.
Then after the loud crash you may find yourself beached on Gilligans Island
or some rocks at 4 AM.
Dont mess with marine safety, the sea is always the boss.
If you do know what your doing see here:
