Two questions:
Does anyone know the difference between the 1708 and the 1708B?
Are there any other similar devices on the market?

There are several companies that make SDR antenna switches.

Elad -


DX Engineering -

QRP Kits SDR Switch Module -

The difference between the MFJ 1708SDR and 1708BSDR is outlined in the ad below. The B is worth the extra money because it has many improvements including wider frequency range, addition of a hybrid port splitter and better receiver isolation.
