That's an 850 Mhz 5/8 wave antenna, commonly sold by Motorola for
trunking systems.

The antenna in the photo was made by Maxrad (PcTel). I have others
that appear identical from Antennex (Laird). I couldn't find a
similar antenna in either online catalog. The one's supplied by
Motorola use a heavier gauge wire which I guess(tm) were Antenna
Specialists (PcTel) like this:

This is the closest equivalent that I could find:

I would advise against using this antenna for 152 Mhz and suggest you
get a real 1/4 wave or 5/8 wave antenna.
