I'm guessing the the cost of replacing the TV Aerial and pole was considerably less than the replacement of the solar panel!
So my advice is, if you have solar panels and your TV Aerial is within reaching distance of those panels should it come down and you know your Aerial/Aerial pole is more than 30 years old then prevention is going to be cheaper than the cure.
I'm always willing, at minimal cost to get up to an Aerial and assess the condition of the Pole, Bracketery & Aerial, before, during or after the installation of Solar Panels.
Interestingly, I can age this particular TV Aerial and it's installation by the make and design of the Aerial used at around 45 to 50 years old, so this is as about as old as they ever get before gravity takes over. Ideally it should have been replaced when the Solar Panels were fitted a few years before the Aerial took a tumble.
As a very general rule of thumb, a good quality TV Aerial and it's correct installation should last in excess of 30 years but I am aware of one or two local, unscrupulous TV Aerial installers who will often only replace the Aerial head itself, leaving a rusty pole or rusty steel lashing to fail at the next strong gust of wind.
Placing a new TV Aerial on top of a rusty old pole which in turn is then often attached to old and rusty bracketry is only asking for trouble.
It's extremely rare for an Aerial to detach from from a pole and if it does the coax cable will usually prevent it from reaching the roof, 99% of the time it's the pole or bracketry that will fail first.
I note for whatever reasons my website is now getting seen by many people far and wide from all over the UK who are obviously not within my working / coverage area so if I'm not able to install you a shiny new TV Aerial just make sure before you pay the TV Aerial man that it's also attached to a shiny new pole and bracket too!
