Its very unlikely that a small FM transmitter had anything to do with damage to the Loop. I'd look for another cause. One possibility is static electricity in a dry shed?

I understand 50Ω and sometimes 75Ω are standards for common coax cable. For phased wiring of receive antennas, ingress must be kept as close to zero as possible, twisted pairs (or Cat5/6) are good
