Tv aerial question

[DevonLady]

I found this on my lawn, under the aerial on the roof. My tv is absolutely fine, should I get someone out for this or not bother?

If it still works probably not an issue unless anymore decides to fall and injure someone.

Have a look up at the Aerial if it has both theses bits ringed then it's not from yours.
It may be from a neighbours or old aerial.

it's a dilithium crystal separator. capt. kirk will want it back.

 

[DevonLady]

Here is our aerial. Looks like it is from ours but just wondered if it was an important part didn’t want to call an aerial person if not necessary

The only worry is the other part falling off and injuring someone.

Just a thought as daft as it may seem. Is that aerial in use? Is there another one in the loft?

 

[DevonLady]

I don’t think there is one in the loft, no. I didn’t know if the bit that fell off is an older aerial and the other taller part is the actual working aerial.

looks like half the reflector has broken off. if the TV pic. is OK, then I'd not bother till the other half joins it ready for the scrap run.

Ok thank you. What does the reflector do?

 

[telectrix]

the reflector reflects the signal back and into the coax that's connected to the box just in front don't know the full technology, but it just works.

You missed out the 'driven element' that sits in front of the reflectors... it's this that is connected to the coax (or 'feeder' as it's more generically called). This type of aerial is called a Yagi...

...just sayin

You missed out the 'driven element' that sits in front of the reflectors..

also the PCB Baun that coaxes a Balanced signal
(opposing phases signals)
Into just the core of the coaxial cable.
..Since the change over plenty of transmitters are kicking out more power , so may be of little consequence.
Birds perching on it may not have helped !
