I took my dipole antenna out and re-installed it in the circular filing cabinet then I installed one of these rubber flexible antennas through roof. Behind radio in cabinet there is a access hole in wall where speaker, power, coax etc. come in from, I took measurements from other side of wall (bathroom) to skylight then went on roof and drilled hole which ended up being between inside bathroom wall. I dropped coax down inside wall and picked it up in access hole then plugged it into radio, Voila! Instant improved reception
Mounted antenna than sealed it with Dicore roof sealant. I also removed trim from skylight above shower to get access between roof and ceiling to move insulation so it would not wrap around drill bit. After radio and skylight trim were re-installed mod took about 2 beers or 1 hr 15 mins. It was well worth it.
