Yes, in times-past I installed a number of 'self-help' systems [unlicensed] to brong Colour! TV to parts of mid-Wales. A Yagi pointed at Blaenplwyf, a "masthead"-type amplifier to drive 50 yards of coax over the top of the hill, another masthead-amp, and another Yagi to launch the signal down the valley to the otherwise-TV-deprived locals. Physical antenna-separation coupled with different polarisation meant we could run 30dB of amplification and still not get any feedback issues. Swapping-over the old tractor batteries used to power the amps every month or so was done by an ancient guy called Meirion and his Welsh Cob pony!
