Had a well known, very good reggae performer at the venue last night. He brought his own wireless dual PG58 setup. It's one of the worst vocal mics I've worked with. Woofy, too loose of a pickup pattern, required a lot of notching to get it stable in the house as well as monitors. I got it useable, but man, it shouldn't be that hard. Blah! I should probably recommend an upgrade to them to at least a setup with standard SM58 capsule. At least there were no RF problems. The BLX288 receiver has no external antennas so you're stuck with what you got.
