I recently purchased a new magnum S9. This one has 1969 finals in it. Are these 1969 finals better than the mosfet replacements? Or about the same? I also plan on using 18 ft' of LMR 400 microwave systems. My antenna is a flat side blackalcapone. Later I will run a fatboy 2x4. Will this type of coax work with a CB? Thanks for the info.

Yes..
It is Excellent coax..
Likely more then most would use in a car though.
However if you can fit it and willing to install it... Go For It
as to the finals...not my Expertise..lol

I agree, plus that coax is stiffer then a wedding night peter and will be a pain running it in a mobile.
The Magnum S9 is a great radio. The dual 1969 finals are just fine, the industry has switched over to mosfets that's all. If your radio works leave it.
As far as amplifiers, a 2x4 is not the best option. They were made for a low powered radio, your S9 is a pretty hot radio and will overdrive a 2x4. You will want a straight 2 or 4 pill that's class AB.

why 18 foot? why not 5 foot or 2000000 foot? why LMR 400 I mean RG8x at 50 foot used at 25-30Mhz is about 0.75db loss well at least the JSC 3060 mini8 is
the time microwave LMR400 is 0.35 at 50 foot at 25-30Mhz, just not worth it, not when quality JSC 3060 mini 8 is $0.40 a foot or less and LMR 400 is like 4 or 5 times the cost if I recall

A friend of mine gave me 18' of LMR 400 with connectors already attached. So I guess I'll go ahead and use it. 18' just happens to be the length he gave me. If it were 5' I would've taken that too! Or 20000'. A gift of free coax was given to me.what am I gonna do not accept. "Oh no its not flexible enough, can I please have some rg213 as a gift instead? " SMH

So you're not really a mean old daddy! :laugh: It's hard to pass up "free"!

Yea most people use a mini 8 or 213 coax, this LMR stuff seems like overkill. A bit Extreme but I'm curious how it will work! It certainly can't hurt. I like the solid copper semiconductor as apposed to braided. This should be interesting ...or maybe not. But stay tuned
You get what you pay for . . .
Buy cheap coax and replace it every 3-6 years - depending on the amount of exposure to UV, heat/cold. wet/dry it gets - or buy a piece of coax that is made like it should be made and not have to deal with it for 10 years or so. Not to mention, if you have a run of 75 ft or more; then it can make a huge difference to signals received as well as how much power it soaks up before it gets to/from the antenna.
The quality of materials used in making coax varies. The outer jacket, the braided shield, the insulation between the shield and center conductor, and the quality of the copper stranded/unstranded center lead all vary from mfr to mfr. If you have ever bought Radio Shack RG-8 and used it, it is the closest thing to a dummy load you can find. But there may be worse coax than that too. Take a piece of it apart sometime and you can/will see why.
