Hi Folks,
I have a peculiar problem getting reception with my digital usb TV dongle used with my laptop (Macbook Pro)

Dongle is an Elgato EyeTv DTT version 3.2.1

With the elgato supplied mini 'whip' antenna reception is ok when i position it correctly
With an old caravan antenna connected reception is ok.

However when I connect it to our roof mounted 'phased array' antenna I get no signal at all. BUT (here is the confusing part)  if I connect our Kogan LCD Tv to the roof antenna I get the full array of digital, analogue & HD channels! Also if I connect the Kogan Tv to the old caravan antenna no problems.

So why can't I get a signal with the EyeTv using the roof antenna?

Thanks

Cuppa,

Where are you located and where are you receiving your signals from (eg: transmitter location)?

Hi Col,
I'm in the Strzlecki Ranges, Gippsland. The TV transmission tower on the top of Mt Tassie is within  'spitting' distance, & line of sight. It's on one hill top, we are on an adjacent hill top.

I found USB tuners to be very sensitive and a pain in the #$%^. Try antenuating/reducing the signal from the phased array.

hi Debruis,
Probably a dumb question, but how would I do that?

Cuppa,

Being so close to the transmitters is probably resulting in very strong signals overloading your tuner, producing high error rates, which your tuner can't decode sufficiently.

Some tuners cope better than others with this situation.

Attenuation is usually the fix for tuner overload...... how much attenuation that's required is difficult to determine without accurate signal measurements, however, an educated guess would be 12-30dB.

You can purchase attenuators in fixed values, connecting them together to obtain the required figure and there are also variable attenuators, which work by turning a knob, like a volume control.
