How good is the TDR?

Hi guys,

I had an open circuit appear in a run of LMR coax burried underground of over 200 feet. Using
the AIM I was able to dig down and locate it, within a foot of what the AIM calculated.
It looks like a gopher went thru the conduit and thru part of the coax!

70 cm Dipole Antenna

This is a screen shot of a 70 cm dipole antenna as shown on an AIM UHF. 
The data on the right side corresponds to the frequency where the cursor (cyan) is positioned near the point of minimum SWR. 


Don't forget the optional protective case for your AIM UHF analyzer.

The case uses a water-jet custom cut high density foam insert in a sturdy black molded locking shell. There are cutouts for your calibration loads and adapters as well as the Power Supply and the USB cable.


BUY ONE - from the Price List 

*Note: you may download the software for the AIM UHF now and it will work in "demo" mode until your AIM UHF Arrives.

We DO NOT ship a software CDROM with the analyzer.
