amplified TV antenna

[Max]

I bought an amplified indoor TV antenna. It has a dial to turn up
or down the amplification. Why wouldn't you always have the dial
turned to maximum. Can it damage the TV?

** But has no control for which channel you want to receive.

So all signals get amplified at the same time.

** Cos strong signals can overload the device or your TV's tuner and cause data loss and picture break up - especially when you are tuned to a weak signal.


> Can it damage the TV?

** Why don't year read the operating manual ??

We have no idea which antenna you bought - rediculous to assume what is the case with one model goes for them all.

This was the one I bought for $14: http://web.archive.org/web/20150901083751/http://www.dicksmith.com.au/antennas/dick-smith-indoor-tv-antenna-with-built-in-amplifier-dsau-l4016

I don't believe it works any better than a $6 non-powered one from KMart.

 

No manual included.

Turn it up too far and you get distortion, which will make things
worse, not better.

Can it damae the telly? probably not.

If you paid for it, it worked! Possibly signal strength is not the
problem where you are. be glad you didn't pay full price.

The worst part is amplifying noise along with the wanted signal, and the
semiconductor device in it also adds some more noise.

There's no real substitute for a proper outdoor antenna - if you still need
a booster, use a mast head type before the run of co-ax, that also
contributes noise that you don't want to amplify.

And there's nothing it can do about all the multi path reception which
caused ghosting on analogue television, but can render a digital signal
unusable if it goes beyond a certain level.

Its worth understanding antenna design - some are more directional than
others.

Most installers put up one with a moderate number of directors and a big
"farm gate" reflector because it looks the part. Where I am, a log periodic
would've been far better, but multiple path reception isn't a big problem
here.

Some Radio Hams work adjacent bands, so their publications can be a gold
mine of info on antenna design.
