Here are more details of the chase and some artsy pics that might be of interest….
Reflectometer sweeps of the antenna feedline connected thru a 5-foot, 50Ω test lead and the test lead terminated with 50Ω and 10kΩ for comparison.
(5' lead + 17' feedline to antenna)
(5' lead +50Ω)
(5' lead + 10kΩ)
RF sweeps of Sprint channels with radio registering (service detected) and idle (no service).
Instrument set to hold peak readings.
The terminator refitted with a 10k resistor and the tube that was later placed over the resistor
Radio indications that appeared after connecting the 10kΩ terminator with the resistor unshielded.
(Much lower received signal strength)
(First time I ever saw "1X" service appear)
Radio indications after connecting the terminator with the resistor shielded by the tube.
(After 25 min but still sniffing for rat. Lights are on, nobody home?)
(After an hour)
