Best Low Loss Cable and Balun

I'm going to reconfigure my rooftop antenna and plan to re-wire the entire installation. I'm using a CM 7777 preamp with a single Hi-V/UHF antenna (50 feet of cable required). What brand is the best low-loss balun available and low-loss RG-6 cable available? I'd like to optimize the signal I am getting. However, if I'm using a preamp, is the loss factor on the cable that important since the signal is amplified on the mast?

RG6 is RG6.
Any balun will be fine.
AFAIK... there are no "low loss" baluns or RG6.

I use times-fiber quad shield rg6, a more pricey but top quality cable, but in general, as Ratman says, they are pretty much the same. You won.t be able to tell any difference in the scenario you are in.

I like the CM94444 balun:

If you can not measure it, you can not improve it.

Belden 7915A. Excellent shielding, solid copper center, tested to 3 gig, and no special connectors required like quad.

Baluns are not made well in my opinion. They just seem cheaply made for something you are hanging out in the weather. I use mastic on them to protect them from the weather.

(LCD - Sony KDL - XBR4) (Receiver - Sony STR-DA4ES)(Blu Ray - Oppo BDP-83) (PS3)( Dish Hopper DVR With Sling) Speakers (L & R - Paradigm Studio 20) (Center -Paradigm CC-470) (Surrounds & Back Surrounds - Paradigm SA-15R in walls) (Subwoofer 1 - Sunfire HRS-12) (Subwoofer 2 - Paradigm PW-2100)

I also use Belden 7915A for all the reasons SkyTrooper listed. www.broadbandutopia.com sells it in cut lengths with Snap-N-Seal compression connector.

I also only use the CM-94444 baluns because the leads are solid wire, not stranded with a cheap U-blade crimped on the end.

Philips OUTDOOR Balun (unknown part number) was measured in 2009 by Johnrmckee to have between 0.5 and 0.9 dB across entire VHF and UHF Bands....no other posted Balun measurement comes close to this performance....but I have not seen any RECENT measurements to confirm that currently available parts still provide this level of performance. Most other Baluns, incl. Channel Master mentioned above, have higher Loss, esp on higher UHF Frequencies:
