A:Answer Thank you for your question! The length of coax largely depends on the outside signal. We typically like to see all lengths under 100 feet where applicable. However, if your starting signal is very good, we may be able to add longer lengths. The lengths that come in the kit are the minimum FCC requirement, so we try to utilize only what comes in the kit for best results. We recommend reaching out to us directly, so we can obtain signal readings with you to help determine what lengths would be appropriate for your application.
