Shielded Twisted Pair Solid Versus Stranded Questions

I currently have 4 pair unshielded twisted pair cat5e cable running throughout my home. I ran two 4 pair wires to each location, 1 for phone and 1 for data.

For some reason I am picking up a radio station on my phones. I can't believe this is happening since I thought the twists would reduce all interference (versus old school untwisted phone wire). I think the radio station is coming from somewhere in my house because I don't hear any radio station when I connect my phone to the DMARC outside.

I would like to replace certain runs with Shielded cable since I am picking up a radio station on some of my phone lines.

I have found lots of SOLID shielded twisted pair but very little STRANDED shielded twisted pair. I have never used solid cable before and am a bit weary.

(1) What is better solid or stranded?
(2) Can solid cable be punched down to a 66/110 block just like stranded?
(3) With shielded cable is it important to have shielded connectors on the end, shielded keystone jacks, etc?
(4) On my phone cables I have one pair not punched down (brown/brown white), could this be picking up the radio station?

Thanks,

Chris

SOLID (1) What is better solid or stranded? - SOLID IS EASIER TO WORK WITH
YES (2) Can solid cable be punched down to a 66/110 block just like stranded? SHOULD BE NO PROBLEM AT ALL
YES (3) With shielded cable is it important to have shielded connectors on the end, shielded keystone jacks, etc? OF COURSE IT MATTERS, BUT LESS THAN THE LINE ITSELF
YES (4) On my phone cables I have one pair not punched down (brown/brown white), could this be picking up the radio station? I'VE DONE THIS MYSELF BEFORE

You might just consider finding the source it's self and shielding it. Might be alot less work.

Hi Lazarus,

Thanks for the quick reply!

One other thing I forgot to ask. Do I need to get different keystone jacks for solid cable?

Thats a definate MAYBE... It depends on what youalready have, but alot of Jacks are made specific for Stranded vs. Cable. You wil have to look at your packaging and hopefully its says something about that.

Before changing cables, try the couple thing.
Make sure yuor DMARC is propertly Ground it.
Second Try cheap radio shack line filter for phone line.

It may help with yourproblem.

you may be getting it from one of the devices plugged into the line due to a  broken filter in a phone or answering machine sending interferience into line.  try removing phone devices one at a time from the phone line.  This would explain why it isn't at the dmarc and is inside the system.  Also try a ferite filter as you enter the building - Like Xrok said is a good idea. This knocks down AM radio from getting into the line.  But any wire stranded, twisted, solid can be a radio antenna.  the Engeneering of the twisted pair only reduces it.
