Recently bought USB TV Tuner: Compro Videomate U620F
Finding that only ABC and SBS is picked up with included antenna. This is
not so bad since the other channels are mostly rubbish, but I have a few
questions:
1. Do the ABC and SBS broadcast stronger signals because they are government
channels and they are required to provide a service?
2. What influence does the length of the rabbit ears of indoor TV antennas
have on reception?
3. What influence does electricity-powered signal amplification have on
reception?
4. Do external house antennas rely on electricity?
5. What would be the best way to improve reception using an indoor antenna?
Antenna size/length? Electricity powered signal amplification?

Re: USB TV Tuner

Fully extended, they should be tuned to the middle of the TV frequency
spectrum.

Height is always a factor but that is mainly to get above line of sight
obstructions such as houses, trees, etc.

From no signal on analogue to just acceptable. Digital is more picky.

Apartment buildings where signals are split between multiple apartments
usually use amplification. Houses only need it if the signal is low to
begin with.

Get a powered antenna that has the highest gain.

Amplified antenna will be your only option. I think the digital TV
signals occupy a slightly higher spot in the spectrum so a standard UHF
antenna will work but may degrade at one end. Get one suitable for
digital transmission and you should be ok.
We use a signal booster on the TV in the bedroom - too many walls, too
many trees, too far from the outside antennaa. Used to work on analogue
quite ok but some channels snowy. No good whatsoever on digital. May
need to install a splitter and run a cable from the outside antenna to
solve my issue.
In your case, I suggest you either borrow a amplified antenna and try it
or get a guarantee from the shop that you can return with no penalty if
it isn't up to scratch.

** Err no.
Fully extended they tune to channel 2, half extended is channel 7.

** You seem to be unaware that DTV is mainly on VHF channels in all capitol
cities.
The VHF channels used are 6, 8, 9A, 11 & 12 plus a couple of UHF channels
for SBS etc.
DTV antennas for capitol city use are quite compact and cover all the above.

Re: USB TV Tuner

OK, that's different to the instruction sheet that came with my
amplified rabbit ears. Reccomendation was to use it fully extended all
the time for best reception and, at less than that, the signals degrade
no matter what channel I'm tuned to. It is a Yum Cha brand however.

You'll have noted that channels below 6 have been excluded hence the
upswing in the spectrum that I mentioned.
