Sorry I missed your post, and I hope that you return to get a direct answer.
The answer is - the best wire you can buy for any UHF / VHF installation would be a good Quad Shield wire with as low of loss as possible.
Communications wire - is all COPPER. The price is probably 4 times as much as regular RG 6 Quad Shield with a copper center wire and a braid outer ground.
As per your request, the most recommended wire - is Belden 1829 AC wire.
If you cannot find it in your local stores, don't dispare - you can buy it from solid signal in any length you wish.

All cable has loss and the higher up that you go in frequency (VHF to UHF) the more loss that the cable has.
If you start with a low level signal at the antenna and then butt it into
coax cable you are going to have less come out at the end than went into it from the antenna.
The amount of loss depends upon a number of factors, cable type and cable length are the two most important.
Cable is rated in db loss per 100' at X MHz (frequency).
RG-6 cable is the cable most used in TV use.
Like all things there is good RG6 and not so good.
Belden 1829AC Coax - Series 6 has a loss of 4db/100 feet at 500 MHz (TV Channel 18)
Channel 32 is 580 MHz
Channel 52 is 700 MHz
A 5 db loss at TV channel 2 the cable would have a loss of 1.4db.
So at channel 18 you loose more than 1/2 the power in 100' of cable between the antenna and the TV.
Here is the Quad Shield wire that is sold in Lowes
Signal Electronic Cable
RG 6 QUAD 18 CCS 75C
Part number # 92041M508
Only 3db/100' @ 400MHz & 6db @700 MHz (Channel 52).
4.48 DB loss at 500 Mhz.

3 dB = gain factor of 2 (actually 1.995)
-3 dB = a 50% loss of signal
Stay away from RG 59 and all other old style cables, they will only cause you problems in the long run. It's too much information for me to type this late at night.
One thing you need to know is that you want to use Quad Shield wire and not regular RG 6 wire, not only because of the lower loss rate but also due to the fact that the shielding keeps out most of the noise.
That is especially important if you wish to receive a good signal or if you need to use a pre amplifier.
If the signal you amplify is crap, all you will end up with is more crap coming out the other end.
