Bear in mind if you put the OTA signal into the multiswitch, you will need to amplify the feed into the switch and a distribution amp would not be of any real use. A high gain low noise preamp to amp the single feed would be better. If you use a distribution amp you could use a diplexer/combiner on each feed I suppose. You will need about 6db gain on each output to be effective to overcome the two diplexer losses.

Alternately, you can use a powered multiswitch like the Spaun DMS5802NF that has an adjustible amp for the OTA built in. Most installers don't care for the Spaun due to the cost, but in some instances it is a good solution, especially where long coax runs are encountered.
