Just Sharing This LNB revolver

Revolver
One of the newest and unique feed systems we provide is a rotating multi feed mechanism (Revolver) that can be installed on the most popular offset reflectors available in the industry.
This product is ideal for operators that want to use the same reflector for multiple frequency bands. Basically you can have the same reflector up to 4 feeds systems (Tx/RX).
This complex system does place the feed of your choice on the focus of the offset antenna. In addition to this feature each individual feed has his own polarization motor so you can interchange automatically the feeds and also set the desired polarization.
The Revolving Feed Positioner (RFP) is based on a highly precise backlash free motor that gets the commands from our APX 500 web access controller. The individual feed polarization motors are also a light, compact and specifically for this application designed mechanisms.
The bottom line is that as long the reflector is designed to support the highest frequency of your choice you can select automatically the frequency band and choose between Ka, K, KU, X or C Band. It will be even cheaper to use this mechanism with two 2 port feeds instead of a four port feed in case you application allows this.

Damn...

I have seen similar mechanism installed on Fibo120 on one of the roofs in Nijmegen, little bit smaller though.

I wounder how they get around the twisting up of all the coax, the motor would have to go backwards to get back to the first LNB, otherwise you would have a big twisted up mess of coax.

How much does that cost and how much would Wim charge for making one? ;)

Exactly my thoughts Terry, to help prevent this the lnbs need to move up/down/left/right for it to be practical.

I do not think they turn mechanism all around and separate LNBs are also not turning 360*. It goes one way till the limit and then goes back. There is no other way.

Thats the way I designed my lnb changer .
A bit off misleading showing the Revolver without cables , I think it looks quite messy with all the cables and switches

Looks excellent.
