Reckon which antenna goes with a Garmin GTX330es?

[DKirkpatrick]

can't find it on Garmin's website... grr...
I think it's a blade antenna. Is there special cabling or spec for the cabling required?
Would APPRECIATE the coaching!

Manual requires TSO-C66 or C74 approval for the antenna and double shielded 50 ohm coax (typically RG-400 is used). There are both blade and rod/spike antennas available from several manufacturers that meet those specs.
