Extension Antenna Cables
Government regulations severely limit the output power of wireless microphones. For a comparison, mobile
phones connect to towers miles away, but wireless microphones barely reach 300 feet line-of-sight. A mobile
phone is similar to a lighthouse that shines to the horizon, while a wireless microphone is like a penlight that
barely casts a shadow on the far side of a dark auditorium. Microphone power limitations make extension anten-
nas systems a critical component of every wireless microphone system, and coax cables are a critical part of
every antenna system. There is no room for error.
ClearOne provides antenna kits that includes the extension antennas and the cables. The cables are cut to
length, properly terminated, and individually tested at ClearOne operating frequencies. ClearOne also provides
extension antennas without cables, but it should be noted that we have found serious errors in the spec sheets
published by two of the industry's largest and best know cable suppliers. Had our clients purchased and in-
stalled these cables, their microphone systems would have never worked properly, and the antenna cables may
have never been identified as the cause.
Plenum Rated Cables have a special coating (usually Teflon) that does not give off toxic gasses and smoke when
it burns. Some building codes require plenum-rated cables, but longer plenum cables are considerably more
expensive than standard cables. Kits with longer cables are available with plenum or standard cables.
ClearOne systems require 50 Ohm Coax Cable with a total line loss
less than 15 dB at 900 MHz.
