So far I have looked at Hills, GME, Matchmaster and Jonsa and have not found anything that suits. Does anything know of anything that will work?
The bunbury digital channels are 30-37, so even a diplexer that has channels 1-69 on input 1, and input 2 only has 30-37 will also work.

Read Get the Best Reception, Southern WA and read the links.
You will notice the following;
ABC & SBS have identical programs on Perth, Bunbury and eventually Mandurah digital transmitters. So you you can use the VHF input for Perth commercial, and UHF for ABC & SBS and the eventual GWN, WIN +.
ABSW and SBS are already on air
Hopefully Mandurah will get digital translators on Turner Hill Pinjarra.

I need to change my perth antenna as i am getting a bit of impulse interference through my current setup (hills opimax) and i was hoping to install a new diplexor at the same time so all I need to do is turn my uhf 90deg toward bunbury when gwn and win are online.
I rarely (never) watch sbs anyway, so if I cant pick it up from bunbury as digital, i will just have to watch it from pinjarra in analogue until they upgrade that to digital as well. Then I can get away with a matchmaster j35bf amp to do the job.

A couple of issues,
GWN analog is on channel 3 in Bunbury which is not receivable using a UHF antenna.
Turning the antenna around to face south will also require you to rotate it to horizontal as well. You should then be able to get WIN analog, ABC & SBS digital.
If you want GWN, you should leave your existing antenna pointed at Pinjarra, connect it to a band 5 diplexer with a new phased array antenna for Bunbury. A second VU diplexer would then be used for Perth.
You must remove the Hills omnimax, because it will pick up impulse interference and the UHF section will stuff up all the other UHF signals.
It is up to you on how far to go. I think Laceys.TV have the diplexers.

But the Optimax is definately going, as impulse interference is a problem. I am tossing up between a Fracarro LP345HV, or a VHF Band 3 only antenna to replace it. I figured that since I am only getting band 3 from perth, there is no point in haveing a antenna that receives 3 4 and 5. But I have heard of excellent results from people with the LP345HV, and its also a cheaper option.

Do not get the LP345, because you do not need or want UHF. It is no where near as sensitive as a 11 element Yagi.

So I would be best off with a Matchmaster DR3010 Band 3 Antenna or similar to replace my Optimax. I have wideband amp, so I will change that too for at Matchmaster J35BF amp, which has 2 inputs, Band3 and UHF.
Thanks again for all your help.

Unfortunately GWN has not said when they will go digital so you may be stuck with analog from Pinjarra.
