Hi Carl,

By the numbers:
(1) So how do I calculate lengths for other frequencies? ie 121.5MHz,
146.73MHZ, 123.0 MHz

By the proportion to the original frequency (this is called scalable).
This usually implies thickness too, but the variation of your
frequencies is slight enough to disregard. Besides, you need to
anticipate some trimming using the SWR meter you are asking for in
(3).

(2) Any chance of damaging my Vertex Standard VX-700 if I start playing
around with this?

Not particularly for low power and modest SWR (and probably not even
immodest SWR).

(3) Where can I finde a descent but cheap SWR meter?

Radio Shack.
