Hey OM:

Find yourself an old RCA/GE TV, well a few years old. Like with a
CTC103 and no earlier than CTC77 chassis, yank the UHF front end
transistor out of the tuner, it'll be the one closest to the RF jack.
The VHF front end is good to 216Mhz and the UHF is good to 900Mhz. And
they are all N channel.

I wouldn't worry about noise figure at 144Mhz unless you are doing
EME.

I used to make a living repairing RCA/GE tuners
