That last link is a low power VHF amp for use with a handie scratchy, to boost power output.
On edit:
If that is a vhf radio it probably would work if you can remove the antenna and attach some coax.
Yes, that is a VHF hand held radio.
As long as the MURS radio output meets the spec of the amp should work.

The first link I can see is not a amp, it allows DC to feed together with low power rf to bias transistors possibly, in the microwave range, it's not a amplifier.
