Shure and AKG antenna

(1/2) > >>

Bill Hardy:
Hello,
I have 8 AKG WMS 450 wireless systems, with PSU 4000 power supply and two PS 4000 antenna combiners. All in the 650 - 680 range AKG band 1.

I have recently purchased one each in the AKG band 7 and 8 to replace two units of band 1.

I need to replace my antenna to a wide band, my question is.

(1) Do I have to use AKG or can I use Shure UA870 (470-698 MHz) which is about 100$ cheaper?

(2) Do I need to upgrade the antenna combiners to a wide band?
If so do I need to replace both or can I get by with just one, seeing I only have 2 units in the lower range at present?

Thanks Bill

u can use the Shure UA870 as the fall within your working bandwidth. If your AKG Combiners are filtered, then they will filter out unwanted frequencies anyways. Just make sure they have power inline to feed the Gain on the Shure paddles.

Any 50 Ohm UHF-band antenna will work. RF is RF, as long as you have the right connector (BNC).

Yes, because the narrow band units will filter out everything outside the band they cover.

Yes - you can change only one PS4000 for the wide-band version and you'll have what you need. Your existing PS4000 would cover four of your existing mics, then the new wide version would cover your two new mics and two existing mics.

Karl Winkler:
Just remembered something: the wide band antenna splitter needs to be first, then the narrow-band unit. I.e. antennas>wide band splitter>narrow band splitter.

Theoretically.  ;)
