Thread-topic: What do you recommend for FM transmitter antennas?

Best coverage is usually with a rototiller or slanted arrow types.  This is particularly true with hilly terrain.   Ring stub types are best over flat terrain.  My company uses ERI for higher power installs (full class-A and up) almost exclusively.  They’re not the easiest to tune, but once they’re set they perform well.  For something like this I’d not use the Nicom, presumably the BKG-77.  We use a lot of them on lower power installs including translators, and while they work OK, I’m not happy with the VSWR at the band edges.  VSWR approaches 1.3:1 especially at the bottom of the band.  They’re indispensable if you’re doing a diplex or triplex, though.

We're looking at putting in a new FM station soon. I'm wondering what folks prefer for transmit antennas on a budget! This will be a 6,000 ERP station with about 4,000 TPO so a 4 bay antenna. We're looking at - BEXT, Dielectric, ERI, Jampro, Nicom, PSI, Shively, & SWR. Which do you prefer and why?
