If you look at the auctions linked from that one, you will find dozens
of other listings for similar multi-band antennas -- some of them
considerably less expensive than the Novatel.
Note that the Novatel information admits that the antenna is not a choke
ring design, but instead claims that it provides "Choke ring antenna
functionality without the size and weight." Also note that the Novatel
datasheet makes no reference to it being a survey-grade antenna.
I did not look carefully at the listings for the other tri-band "survey"
antennas on ebay, but I assume the same is true of them.
Best regards,
Charles
