The UHF aerial on our roof looks to me like there's part(s) missing... what do you think?

Been having signal issues (pixelation etc.) and wondering if this is the cause.

And the tree.

Spark Max Fibre using Mikrotik CCR1009-8G-1S-1S+, CRS125-24G-1S, Unifi UAP, U6-Pro, UAP-AC-M-Pro, Apple TV 4K (2022), Apple TV 4K (2017), iPad Air 1st gen, iPad Air 4th gen, iPhone 13, SkyNZ3151 (the white box). If it doesn't move then it's data cabled.

UHF aerial looks fine, you obviously live in a high signal area.

I see a duplexer on the mast.

If it was me I would run a whole new cable from the antenna to the TV ( RG6 ) and eliminate duplexers and joiners.

As a former aerial installer I always recommend using and installer with the proper tools for the job, believe it or not too much signal can give the same as not enough signal.

I have seen a needle on a signal meter barely move and dropping the aerial down 1m it was more than sufficient.

Get rid of the diplexor you don't need it and it will only be creating signal loss.

If it like most old vhf uhf diplexors it will be full of cobwebs dirt dust and water
