Hello,

i am out on the coast - have tuned into the dvb-t signals from the palmerston north transmitter, all channels on the 690000 frequency have a very low signal quality strength (<30) so cannot view any channels on that frequency, (channels TV1,2,TVNZ6, TVNZ7,TVNZ Sports xtra) - no video erratic audio

channels on 778000 frequency (tv5 maori tv, tv22 parliament tv, tv30 central tv (maori tv),tv100 Freeview HD, ch 242-245 reserved channels) are received much stronger (currently 75 - 85% signal quality) good picture and audio

uhf aerial recently upgraded and tuned to the PNorth transmitter site with a spectrum analyser, results are the same

can receive all analog channels.

the dvb-t channels on the 2 frequencies are clearly at much different signal strengths.
Rang freeview but not much help there.

any suggestions?

perhaps you are just too far away from the transmitter.  Baring in mind the transmitter is on a hill near Ashurst, not directly in the city.

maybe someone like Cyril might be able to advise whether a masthead amp will be any help.  Or even a high gain antenna.  But i'd seek advice before shelling out for something like this.

I live on the eastern edge of the city and get pretty much perfect reception.

Which coast, Wairarapa or Wanganui. Presume the former, the coast is not part of the planned coverage area, any reception would be good fortune.

Hello,
thanks for the replies :)
im at foxton beach, in a reasonable coverage area on the freeview map,

am wondering if the xmitter for the 669000 frequency might be at a lower power level
than the other channels?

All 3 from Wharite, channels 48, 50 and 59 have a power output of 45 dBW - 30 kW.

thankyou for the information.

my curiosity is simply why 2 frequencies are received at a diferent signal strngth
 to each other from the same broadcasting station,
in the meantime though i can happily watch content on maori tv and ch100 freeview test hd chanel :)

cheers

Sounds to me like you could have a layering issue. Try shifting the antenna, Often just raising or lowering the antenna over a 2-300mm range can shift you through a peak or trough in signal as a result of layering, If that is to no avail then try another antenna site. All this assumes the antenna, cable and connections are in good condition, sometimes not the case when living near the sea.

A amplifier is possibley needed based on your distance from Wharite, however you need to ensure a non amplified antenna is working at its best before you resort to an amplifier.

Hi,
thanks for the replies, much appreciated.

Have got another thought on the issue, im aware there are some groups of quite tall trees in the line
of sight from aerial to xmitter many km away, this might be a possible interferrence
i will look further into this and ascertain if the trees might be a possible issue.

thanks
