In some respects SWM is better than DISHPro in the you can supply numerous compatible tuners with a single cable. The SWM5 can run five FTM tuners and the SWM8 can run eight off of a single cable. For more than a couple of legacy tuners, you'll need a conventional multiswitch too.
The second benefit of the SWM is that you can diplex on it for incoming OTA or outgoing backfeeds.
