Please could somebody tell me the best cable (compromise between cost
and loss) for use with an external Yagi antenna connected to a mobile
phone. I live in a Very poor reception area, and I need to fit an
external antenna. I have found somewhere that sells 10 element Yagi's,
and I can mount the thing as high as need be, but I read somewhere
that the longer the connecting cable, can negate the benefits of long
mounting poles. I have freinds in the surrounding area that have the
same problem, so I could do with a "rule of thumb" that I can use for
fitting these things. The shop where I got the antenna from is
offering me RG58 cable for this purpose, which is cheap enough, but is
it the best compromise for what I am trying to achieve? Your
assistance would be most welcome.

If you need to stay cheap, use good quality RG 6. We used this stuff at 2000
MHz. You can go to the Belden or Times Microwave web site, and find tables
that list the loss of various types of coax at common frequencies. BTW, at
900 MHz, RG6 will have less loss than the fat RG8. If you want GOOD stuff,
get LMR400, or 9913. DO NOT get RG58/59/8/8X/8FOAM/213/214.
