<DIV>-- The MFG. expected life of an antenna is about 10-15 years. Of course they want to sell you a new antenna! YMMV Good cable may cost more than a new antenna.</DIV>

<DIV>-- You should use RG-6 Quad Shield for shorter runs or consider RG 11 if the length is over ~100 feet. You will loose more signal at the higher channels first. You may need a Mast head pre-amplifier, these are 'special' low-noise amplifiers intended to account for losses in the cable to the house, and are different than distribution amplifiers.</DIV>
