Antenna Rotater November 28, 2016
Reviewer: CrankyOne from Camas, WA  
This is really heavy duty and easy to install.  I have a large TV antenna on it and not had any problems.  It does a good job ranging for channels and has good pre sets.

A Must for Antenna Fans, but... November 25, 2016
Reviewer: Wolf from Lovell, Maine  
A reliable and accurate antenna rotator is definitely a must for the rural TV viewer who wants to take advantage of the crisp digital signal available over the airwaves. This product seems to work once properly set up. Unfortunately, the setup instructions are printed overseas somewhere on what is supposed to be product manual but in fact is the worst kind of technical instruction sheet I have ever seen. Printed on low budget stock, it is printed almost illegibly small, difficult to comprehend and dispersed among foreign language instructions over several pages.  I ended up writing myself a summary so  occasional visitors others could grasp the manual. I am not able to comment on the rotator's reliability but it looks rugged and should withstand the elements. Another flaw was the fact that the technical description does not specify the fact that special (22g AWG) wire is required carrying an 18 V to the unit. In summary: a promising product poorly marketed and set up.

Light duty rotator for 2m Ham Atenna November 25, 2016
Reviewer: Tom from Northeast Oregon  
Although this rotator and its related controller are designed for TV antennas it worked well supporting a 2m amateur radio antenna.  The controller works as advertised and fairly rapidly.  You know it was designed for TV because there are 69 memory locations representing TV channels you can store headings into.  No worries, I just created a table that relates the heading to the memory location.  It was a economical purchase.

New Rotor for our old antenna November 25, 2016
Reviewer: Anonymous Person from Elkton Maryland  
We received the new system to replace our 30+ year old Radio Shack rotor. I gathered the tools needed; my husband and I got on the roof together and had it changed out in less than an hour. Easy peasy!  I did put Rust penetrator on the old bolts for a few days before we started... made things much easier. Works like new! (It is!)
