Bunching cables

Would there be a problem with interference caused by tye wrapping a telephone cable to a sky cable (externally).

Highly unlikely but you'll soon find out if you do it.

Telephone cable is twisted to minimise low(ish) frequency interference. Satellite cable is double screened (and coaxial) to minimise high frequency interference. Telephones don't use high frequencies and satellites don't use low frequencies. They won't interfere with each other.

Virgin Media runs coax and telephone wire on the same "shotgun" cable and they don't have problems!

Sattelite signals from the LNB to the receiver are in 950MHz to 2150MHz range (this is much lower than what the sattelites themselves use, the LNB is a frequency downconverter). This is well above any frequencies used for phone or DSL.

There is a 22KHz signal used to switch the frequency range of the LNB and this is within the range used by DSL but frankly if your cables are crappy enough to give significant coupling at 22KHz the coupling is probablly the least of your worries.

doesn't cause any ill effects. Bt don't allow installers to do it but this is purely because if the satellite comes out the phone wire comes off with it.

different story with cables carrying mains power, 50mm seperation needed there. good luck.
