If you want EFJ ones, you'll have to find an EFJ dealer. See the efj www site for dealers.
Antennas for Motorola XTS-5000 will work too.

If you just want a cheap aftermarket one to experiment with, you can find 'em on ebay. Search "sma-f antenna".

KMB is correct, for future reference putting a /\/\oto antenna on an EFJ portable will result in an ever so tiny gap in between the radio and the base of the plastic shielding on the antenna...

Looking at the pictures for the Motorola 5000 and the Johnson 5100 antennas, there is a small difference in the dielectric around the center pin which I believe accounts for the resultant gap when using the Motorola with the Johnson.
