What I wasnt sure about, is where the ribbon terminals actually connect to the aerial (This is the dumb question part). So all I tried was inserting the spade type terminals under the two bolts that connected the aerial to the mast.
Unfortunately the picture quality was not great so leaves me undecided whether I could get Freeview HD. Now it could be that the very old aerial is knackered, or that I was missing an important fitting of some sort that the ribbon terminals need to be connected to?? Even though the aerial is a bit old and rusty I suspect it would still do the job.
So short of buying a new UHF aerial on the off-chance it works, is there some other type of Balun I should be trying (maybe a coax to coax rather than ribbon terminal? Is there such a thing. I couldnt see anything else on Hills website that really helped.
I also managed to snap off one of the spade connectors in the process of changing the aerial direction (the bolts were very rusty).
On a side note - RG6 at Mastertrade $1 a metre v $2.89 at DSE and the Balun was $5 v $10
