Did a installation in Auckland CBD where I needed to install a Freeview aerial and as i had good access to roofspace I bought what i thought would do the trick.

A Digitech flat panel indoor, outdoor UHF III and UHF Band IV with line amp.

Great TVNZ mux 10 strength and 10 Quality pointing at Sky tower.

While the mediaworks mux strength 10 quality >1.

mediaworks not on Sky tower or weak signal?

Need to move out of roofspace to get better quality?

ANY OTHER OPTIONS than that.???

Cheers

You could try moving it's location about in the roof space to locate a "sweet" spot.
Moving just a few inches can make a radical difference.
I had this when setting up an antenna in a low signal area.
Set it up temporarily on a balcony rail and shifting a few inches or degrees made difference between picture and no picture. Just needed to be in the "sweet" spot. Eventually set up on the roof clear of obstructions and signal/quality went to100/90+ on all MUX.

Band III is VHF, 174 to 230 MHz. Band IV UHF ends at channel 34 so this antenna really belongs in the bin first and foremost.

UHF Band IV & V 470 - 862mhz therefore plenty of headspace Spyware????? Missed V in my original post.



Yea thanks for the reply's guys so just a bit more patience I suspect.

Is there a inexpensive/hire tool to measure signal strength at receive point as the more and more virtual signage I am doing needs DVB-T reception?

I recently installed a Draco Ant 200 powered antenna in Auckland CBD in a high rise apptartment shoe box. Worked best lying on the floor under the bed.

I imagine that the signal from the Sky tower is bouncing around all over the place inside the concrete jungle so is just a matter of finding your sweet spot.

Perseverance is the key.

Yea i was wondering how much refraction was taking place and whether pointing 215deg and correct angle exactly as per Google maps was going to make ANY difference :)
