Seismic doghouse/recording truck 20kW diesel generator- lower RF interference than gasoline unit

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%) RADIO ANTENNA
