Tim's idea is a fine one. Alternatively, you could use AA2TX's
lindenblad designs.  You can even get away with a simple groundplane
bolted onto a female bulkhead N-connector.

In all these cases, though, the most important addition to your setup,
especially on 70cm, will be a low-noise preamp which is connected to
the antenna by a short run of very low-loss coax, such as LMR400.

Finally, as for hand-held use, have you tried operating your ht with
hand-held yagi indoors as if you were out-of-doors? Depending on the
sort of building you live in, this can work fairly well.
