Oubadah: Assuming I end up using a masthead amp, I have a question about the placement of the power supply/injector:

The instructions seem to expect you to install it at 'A', between a TV and wall plate. That's a bit messy, and I was thinking would I be able to connect it almost directly to the splitter at 'B'? There shouldn't be any logical reason why not, but I thought I'd check...

Should be fine. Normally its easier to put behind the tv though.

You can install it anywhere you want to in the coax cable run between the amplifier and your TV. I have mine installed close to the amplifier and before a multi-way splitter that feeds the various aerial sockets around the house.

I just dropped my UHF aerial off the roof, and it's completely farked now (all the plastics had gone brittle with age).

It was just the standard 91 element Strongline affair that I see on everyones roof.

Should I get another one the same, or is there something better/ designed specifically for terrestrial freeview?

Damn!!
Murphy's law right? ;)

I haven't had any experience with the freeview one you linked, but I have heard good things about these:
http://www.dtvs.co.nz/index.php?main_page=product_info&cPath=3&products_id=74

19dB gain for the dtvs, vs. 9.5 - 15dB gain for the freeview one.
There is probably some spec fudging going on there, but it looks like it is worth a look.

And I see my old one had 14-16dB gain, and is $15 more new, so I think I'll be getting the Engel one.

Thanks for your input.

This seller was very helpful in helping me decide on an aerial. He used some website to determine the land contour between my address and the transmitter then recommended an antenna which ended up being cheaper than the one I was planning on getting.

One thing I observed whilst dissecting my ruined UHF aerial was that the traces on the little PCB were quite corroded. The box is made so that water can't enter directly, but obviously moisture still seeps in.

Should I seal up my new aerial's box with silicone to make it water tight? Same goes for any masthead amp, should I seal up the casing?

No, especially the amp - they get warm inside so it would probably melt the silicone anyway.

For the amount of time it takes to corrode that badly, the rest of the aerial will need attention after 5-10yrs - so just replace instead, its not like they are expensive.
