I use them with no insertion loss at all. There is a version of it with a male end for antenna however I don't see it on Tessco's site. The polyphaser model # is DSXL-MA

We always use LPU's on the CAT-5 but I've never put one on the antenna lead. What kind of line loss does it cause? I don't see that in the Tech Specs. Also, does it come with a male antenna connector side? Dave Hannum On Thu, Jun 13, 2013 at 10:35 AM, Kurt Fankhauser <li...@wavelinc.com> wrote: Can you possibly put a polyphaser on the 9000APC?

The second and third radios have gone bad on the second antenna. We'll probably swap the antenna again this afternoon on this one.

Good drip loops on both the antenna cable and CAT-5 Cables. We actually sealed the entry of the radio with mastic to be sure. The first radio lasted about 10 months. When it went, we first swapped antennas, thinking maybe a lightning strike damaged it (we've had the same effect on signal from bad antenna). That did nothing to help, so we next swapped the radio. Signal back. That lasted about four weeks. Swapped radio again, and signal back. Lasted about 12 hours this time. No visible damage to any of the radios. No moisture found inside. We don't have capability to test in-house. Will send to SWG or Wireless Units to have them take a look.

Interesting mystery! Clearly you don't want to blow more radios this way. Any more clues about what may have happened right before the failures? I'm wondering about weather events. Did it fail after a rain storm? Water coming in to the radio or corroding the antenna connectors might result. And if the antenna's connector is flaky, re-attaching it to a new radio might be a temporary fix, but reattaching it to an old radio might "fix" it too (temporariy). Have you examined the broken radios in the shop? -- Fred R.
