Can anybody suggest/recommend a wireless system that can handle Alembic basses? I'm not talking about those expensive systems that I see the pros use. Rather those systems that sell for ~$50-$70. The only one I found that doesn't produce weird alien sounding noises is the one by Kliq.

For cheap I use a Samson 8R-2 that used to not be not-so-good because TV channels were near the same spot on the frequency band. However, those channels transitioned away up to the higher ranges and now it's in the clear!
