Sure enough, that's what Sinclair says. The 2-Meter range Celwave PD-220-2 collinear antenna that it replaced didn't have any extra stubs or cables, and all of the other "Stationmaster" type antennas I've ever seen over the last 35 years never had anything like this. So we just folded this "stub" over and tucked it inside the mounting tube and put it up. We haven't had a chance to see how it performs yet, but if it works as well as the Celwave, it will be a great antenna.
The previous Celwave antenna still looks almost brand new after nearly 14 years up in the air in the NW weather. We figured it would be time to replace it, so now we have a spare which we'll use to replace a 14 year old Scala OG-4 at another 2-Meter Repeater site, which definitely needs replacing. Thanks to all on the list who replied.

That extra cable in the mounting tube is part of the matching network. Just push it back up inside the mounting tube. Only the VHF model uses this RG142 matching cable. I have used these antennas for over 20 years now and have had excellent results. You can see some pictures of them on our web page.

The new Sinclair 2-Meter antenna arrived (ordered for our 2-Meter channel) and we found a second cable going into the base of the antenna. There's the main antenna connector, and there's also a short length of what appears to be RG-142 cable, hanging out and going nowhere. We've worked with many of these "Stationmaster" type collinear antennas for many years, but have never seen anything like this. The instruction sheet and frequency sweep don't mention anything about this loose cable going into the antenna. Has anyone else seen this and know what it's for? Our dealer that we ordered it through hasn't seen anything like this, either, and was at a loss to explain what it might be. We also ordered a brand new 10dB Sinclair collinear for 440 MHz, and it doesn't have this "extra" cable. LJ _______________________________ Do you Yahoo!?
