Hi Russ
You cant go to far wrong starting with an 817 as it will pretty much do anything you wish!
Ideal for HF, VHF or UHF and will happily run all day on a 5000mA/h Lipo.
In all honesty, looking at where you’re based it may be worth starting with VHF and FM or SSB will both allow you to qualify summits.
And dont go buying any expensive antennas from dealers. As Rob says the easiest antenna to get you started is a slim jim. Mine cost about 5 pounds to make and rolls up and goes into the rucksack. My 4m variant has done over 500 points on the band with one slight service to check that no water had got into the coax.
There are plenty of designs online that use 450 ohm ladder feed.
I.E - 450 Ohm Slim Jim Antenna Project by KE4NU However be aware this is an American website so may not be great for 145 MHz FM.
A better site maybe

Type in 145.500 into the frequency box and low and behold you will have the dimensions for a slim jim that will work very well in the FM portion of the band.
Here are some photos of mine in action, this one is designed to work on 70 MHz
Finally get yourself some guy wires and a 7m fishing pole and you can have some excellent results!
Alternatively have a go at a dipole, this design by John M0JDK
All John has done is get a bit of coax, has taken 19 inches of the plastic outer off and separated the inner from the outer and has put it in a tube. Like John I use mine Horizontal, but you could drill a hole at one end and put a cable tie through and attach this to a fishing pole!
In addition at the feedpoint you could turn 7 turns of coax to make a choke balun. Its dead simple and wont cost you more than 5 pounds, where as you could go online and buy the same product for 25 pounds!
A no brainer in my opinion!
So an 817 will serve you very well, but that saying any of the yaesu single band VHF/UHF radios will be fine!
Hope that helps, save your money on antennas and spend more on the radio!!!
