Skilletlicker,
Mini 8/U Handles 1000 Watts Maximum of Power.
Copper Part #C60-00006
Good for Mobile or Jumper use Felixable & Small.
Need's UG-176 Reducer for PL-259 Connector
Copper Part #C70-05010
213/U Handles 5000 Watts Maximum of Power.
Copper Part #C60-00012
VERY GOOD for outside Antenna's and Tower's and anywhere else. Very Durable / Realiable. 
I also use 213/U for all of my Jumper's and All Equipment in the house.
I Personally would Recommend 213/U for everything.
And it would save you upgrading your Coax at a later date to 213/U if you ever decide to run more power.
Do it right the first time and save time & work later.
Lon

skilletlicker,,check out this site for some good reading on coax basics....i was particularly intriqued by the plate system he uses in hookin his stations coax up...very interesting,,,like the idea of a ground section....

I agree with Tech808 use 213 minimum where ever it will fit. Having said that I used to run heliax up my tower backin Oz but that was only because working in the trade (ran own business designing and implementing communication systems) I always had some "ends" left over. Wish I could afford to buy a roll and 20 or 30 plugs. SIGH! |

It's really here warm weather time to put up my beam now! But after reading these posts what type of coax to buy?
Tec 808 you recomended RG 213 U! But,would not recomend the mini 8/U out side.
I do not plan to run alot of power through it the most would be what ever my 2970 put's out.Not turned up just fixed for the freq's.
And the length I have spent about 1 hour looking over sooooo many posts from the past,and read any thing to anough to go from point A to point B,and then I have read to go with 100,200 feet?
I am kinda partial to the mini coax but if Mr.Lon recomends the thick coax then I will go that way.
Thank you for any input Len

Thank you Mr Lon but how long should I go with the coax?
Enough to go from A to B, or go with 100 feet and roll it up by the antenna.
As soon as I figure out the length it will be ordered A.S.A.P,
When I put the beam up I can get back into the side banders net I found about 50 mile away from my location.

Len,
Figure out what you need to reach your radio and add maybe 15 feet extra, in Case you ever decide to move your radio and the Extra can also be used for New Jumper's.
When you order your Coax just order a 10 pack of PL259's and Reducer's and you will be all set.

i like LMR400 or the LMR400UF
the lmr400 is about the same size as rg213u but it has a copper sleave that makes it hard to bend like the rg213u but when u bend this is stays in place and is as cheap or cheaper then rg213u and i think is much much better.
the LMR400UF is like the LMR400 but is very flexible great for beam setups. this is about 1$ a foot

I am sorry it took so long to chime in.
The difference is the resistance of the cable and velocity factor. Two different cables with the same shielding can have two different velocity factors. This will make one cable 'look' longer to your RF than the other. This adds up to more loss on TX and RX. Secondly, the diameter of the center conductor changes the internal resistance of the cable. Lower resistance means more signal to annd from your antenna (TX and RX). Larger diameter center conductors are better at all power levels, even microwatts during receive. A higher power handling capability means higher performance at any power level.
LMR 400 is my all time favorite cable for short runs. It is not suitable for beams or antennas mounte don a rotot since LMR has a solid center conductor and can only be bent so many times before it breaks. This is one area where a short RG8 jumper is required.
For longer runs, invest in Heliax. It will be the last cable you ever have to buy. |

Hey Lon Thank you for the help on this situation I ordered the coax and the PL259 and the reducers.
Should be here in a couple days.
I should have the beam up by next weekend.
You and your family have a nice Easter.

Hey Lon
I received my coax,PL259's and reducers today that was fast.
But now I think I have another problem I ran across a tower today for only $200.00 for a 60 foot tower,I think it may be a rohn type of tower.
I only ordered 75 feet of coax.*sigh*
I guess back to the drawing board,but all the help you gave me was a BIG help Thank you.
The amp deal it's going to have to wait.
