RADIO ANTENNA
Radio-telemetry system is limited in part by
line-of-sight. A 100-high telescopic antenna
provides longest line-of-sight over 10 miles.
Unit is powered by diesel engine and adapted from
drilling rig Cavity filters in parallel can
focus RF energy at receiving frequencies although
with substantial energy loss (25)
