I think it all depends on the band to be honest but it’s most likely to be UHF 400-520MHz in which case even if if was radiating 100 Watts EIRP it’s unlikely to cause you any major issues if you’re any more than 300mm away.

The impact of RF signals on data traveling through the line would be negligible, the likely impact may be where the coax runs near your Ethernet repeaters or switches but these days even so they’re usually fairly shielded.

Someone with much more knowledge than me may have more insight but I’d feel fairly comfortable with a separation as mentioned above, once again dependent on the band.

Kindest Regards,

Interested in hearing from any RF gurus who have run Leaky Feeder and
unshielded UTP cables, in underground tunnel environments - what cable
separation distance did you use to minimise any noise from the UTP
services that are run in parallel ?
