A dead glass picture tube TV has been standing around for years waiting for me to dismantle it in search for reusable materials. It had also been occupying a corner of a hallway in the house.
I saved the printed circuit board, the deflection yoke, some interconnecting and other wires and two speakers. The rest went in the rubbish. See the PiPs for other views.

Top view of the the co-ax connection point. Years ago my TV antenna was performing poorly so I took it down to check. I found it had a printed circuit adapter, AKA balun, to interface the antenna's balanced dipole element to co-ax cable. I found a printed circuit inductor was open circuit. This was replaced by a thin insulated wire. When reinstalled it work much better. October 2012.

My 2M antenna at home as first installed.
This 2m antenna is constructed from a dexion bracket recovered from a telecoms site ~30 yrs ago, a mobile base even older and a mirror mount clamp. The vertical is the spring and whip I use on vehicles. The ground plane is galvanised wire from a coathanger. The feeder is an RG59 equivalent from a disposal source.
In 2013 the fibreglass whip was replaced with suitable length of galvansed wire in a ferrule from an old mobile phone antenna. It was a nuisance having to climb up there when I wanted to work from a car.

The fibreglass whip plus spring has been replaced by a measured length of scrap zinc plated steel wire and a ferrule from an old analogue mobile whip.

Exeter becomes The Valley for a day for the filming of a Nescafe commercial. Sometime in 1994.
