This is for a PAIR of BRAND NEW 1/2-wave UHF antennas which are a perfect replacement for hard to find, expensive Shure UA820A antennas.
I deal with a LOT of UA systems, and finding decent antennas is a real problem. The original Shure antennas are getting hard to find, and many will not stand upright anymore.
New ones from Shure are $32 EACH! I set off to find a suitable replacement, and have found a source of excellent 800Mhz 1/2-wave TNC right angle antennas. I added a BNC adapter and ended up with a perfect solution. As you can see from the pictures, they are almost identical in size and depth to the original Shure antennas. It took a long to time to find a source for these and ship enough to verify that they indeed have worked perfectly for customers. After four years of supplying these with systems, and now hundreds of pairs sold separately, I have had no problems reported.
As for performance, these are as good or better than the original Shure UA820A antennas for their UA, 782-806Mhz frequency group.
I am an electrical engineer, and have tested and verified their performance.
Also, these will not wear out and droop, as they do not pivot. The right angle is rigid and well constructed of solid metal.
I guarantee these will perform perfectly, and are an excellent alternate choice for all Shure UA system receivers. (U4D, U4S, UC4)
