MPD Digital rg-213 Coax Antenna Cable with Amphenol?
Running about 75'
The radio is a galaxy 2547 with about 200 watt amp to a A-99 base antenna.
Thanks for your opinions!

It will be fine, MPD is a quality brand. The connectors look to be crimped on so check the solder on the center contact, the shield should be fine under the shrink tube. RG-213 has a lower loss spec than RG-8, a 75ft run will be okay, runs over 100ft I'd go with LMR-400. Use a good sealer on the outside connection.

My rule of thumb is and this is using quality coax,
RG58 = 20ft or less,
RG8X, mini8, LMR240 = up to 50ft
RG8 = up to 50ft
RG213 = up to 100ft
LMR400 = anything over 100ft
Anything over 250ft you should consult an "electronics/electrical/mechanical" engineer, they have programs to run the numbers and give you the best specification.

What about height there kev? And if you're bored you can always make yourself a sloped radial system with wire that doubles as guy wires. Do you have close neighbors or are you in the open? Get yourself some good meter action to monitor it as well. It sounds like you are ready for radio fun.

Well, going up 40" to the base of the antenna........
Neighbors aren't too close.
how do you make a sloped radial system with wire that doubles as guy wires?
Sounds interesting!

On the radial deal, long ago I had 2 antrons up. One with no radials and the other I had 3 9 foot sloped wires equally spaced coming off it, terminated with an insulator at the ends, then poly rope for the rest of the guy, essentially creating a sloped radial system. If you look up an old "starduster" base antenna it resembles the radial idea. On my comparo the lower antron with the radials had a needle width better receive on local signals. That isn't a ton of increase but I like to maximize when I can. Now that isn't scientific but it worked for me and is cheap to do. Now it could increase tv and other electronic interference.
