yep, the uhf tuner outpout will be too weak to se eon a scope but you
may be able to use a scanner tuned to 41 to 47 MHz. The UHF tuner
ocsillator will be very unstable compared to the narrowband signals in
a scanner. The drift is not a problem for 6 MHz wide TV signal but
might be a problem for narrow 30 kHz signals etc.

If you work at it, you mat be able to generate an AFT signal from the
scanner to stablize the tuner. Have fun

Also, most cell phone signals are digital these days so you won't be
able to use this method to hear them.
