Is RG58 fine to use for an 11 m dipole lead (no amp used, so no more than about 15 Watts on SSB), with a run of about 50 feet in an attic? Or do I need to use something like RG8X. Or, what other type would you recommend. Trouble is my only cable source in town for RG8X is really expensive, so I was wondering about the RG58. I cold order coax online, but I'm excited to get u and running soon--my power supply just arrived and I built my antenna last night! Thanks!!!
