andrewcnz:

Used to be able to get Freeview via Kopukairua (vert) and Te Aroha (Horz) it depended where you lived in Katikati. The hint is to see what direction the UHF aerials are pointing on houses around you.

UHF is a strange beast. I would have thought Kopukairua would have at least had a sniff here, but absolutely nothing, went back to horizontal and Te Aroha and raised the array, and got the full selection of channels. Sometimes the picture is superb, other times pixelated. I might end up with DVB-S if I cant get a tad better by tweaking the LNA and aerial.

Most aerials in the rural area are pointing to Kopukairua which is the weird thing; Ive noticed 3 UHF aerials within .5km range from here.

Moral of the story is dont listen to locals as to direction of places; I was 25 degrees out on Kopukairua.

The location of the aerial is on the wrong side of a tile roof which is almost the same shielding as a steel roof. I did get most of the channels but the roof attenuation was too great, so its back to DVB-S. Not allowed to have aerial on best side.

Hi Ageorge.

Sounds like you need to get hold of a Signal Strength Meter and do a proper Site Servey for both Transmitters.

Otherwise its a pretty Hit and Miss affair.

Im over in Whakatane and receive Te Aroha Freeview with levels just on Threshold.

Ive found that Ch 28 to be the weakest out of them all.

Just by moving the Antenna 50mm up/down or to the Left and right can mean receiving the Complete Freeview Mux, or loosing some of it.

A spectrum analyzer will show you simultaneously what your levels are for each UHF Freq being used.

Cheers:
