I recently installed a 43 element UHF aerial and pointed at the Haywoods transmitter.  I am at the top of Stokes Valley and I don't think I could get a good signal off Fitzherbit (I'm above the saddle through to Naenae).  I bought myself a JCMatthew DVB-TB01 and ran the auto-install.  I'm getting all of the channels perfectly except for the TVworks channels.  They either break up badly or say signal not found.

I found a thread here where someone mentioned that there was problems with the TV works channels off Haywoods.  Is there anyway to confirm this?  I contacted the Freeview helpline and they just told me to call an installer.
