Best DIY tweak?

Hifisoundguy, I am interested in what you have written but not sure I understand exactly.

Are you basically saying to wrap the bottom portion of the center RG6 cable with Teflon tape and push the tape down tight where it touches the Connector barrel ?

Can you send me a picture ?

Sorry Ozzy no way to post pictures....This is a very easy tweak, your just wraping the (center >copper< pin of the cable) with teflon tape and then pushing the the tape up to the base of the center copper pin. This makes non HDTV look a lot better....sharper..cleaner...brighter........darker colors!

Okay then......
For the tech-savvy, why might this be??

Is this, like the brass screw tweak, a "dramatic" improvement?

If you want

sharper..cleaner...brighter........darker colors!

don't most TVs have adjustments for these qualities? Although I rarely watch TV anymore, if I recall mine does.

DIY solid core powercables, 12-13awg. Mine is shielded too. Cleanest and most powerful current you can get. If you nedd any extension-cable make it solid too. Big powergain!

Replace the in-box powercable from rear wall to off/on-switch and back to trafo with solid too and your boxes will climb several classes in performance.
