Wideband amp required
 

Hi,

Can anyone recommend an aerial amp that will boost TV/FM/DAB signals
successfully? Don't need a lot of gain, just enough to overcome
losses through splitters. 1 in 1 out will do.

Cheers big ears,

Marky P.

The Labgear one works well. We use them as little pre-amps for sat box
outputs, before the signal goes through the lossy channelpass filters.
I think its called an MSA111 or an MRA111 or something. To find out
would mean lifting my arse from the chair, which alas is out of the
question.

An afterthought:
I can give your more information without needing to lift my arse. All I
need do is lift a bit of text from an on-going work and drop it in your
lap. Here it is:

"My favourite device here is a setback amplifier from Labgear, the
MSA111. These are bought in their hundreds by people who really need a
better aerial, but think they can save money by circumventing the laws
of physics and =91boosting=92 the signal behind the TV set. In this
application I=92ve no doubt these amplifiers are generally a
disappointment and go straight back to Argos, but as pre-amps to
compensate for filter losses they are perfect.
An odd problem can arise here. The amplifier=92s output is connected via
a short link to a filter unit that accepts a narrow band of frequencies
but rejects everything else. The input of the filter only presents a
75Ω load at the frequencies to which it=92s tuned. Some amplifiers
seem to rely on a nice even 75Ω load on their output to maintain
stability, and will oscillate under less comfortable conditions. I=92ve
never had this problem with the MSA111, but if it arises and there=92s a
bit of spare signal to waste a 3dB attenuator in the amplifier output
socket will provide a cure.
If the aerial signals are so weak that a masthead amplifier is
necessary you should either use a two stage unit with sufficient gain
to provide the necessary signal levels by itself, or use a single stage
unit plus a setback amplifier. The latter option is probably more
stable."

I've no doubt that this medium (inadequate as it is for anything except
the restricted typography of the infant school) will have turned my
omegas into dog turds or something similar.=20

Thanks Bill! What about the 'one for all' ones? There's a new one
going cheap on ebay at the mo. Any good?

Sorry, no knowledge.

I use Google to prevent the disaster of having to lift my arse out of the
chair. If you *know* something exists Google will find it.

It did, but as Usenet was only ever designed to transport printable ASCII
characters, then it is only to be expected. News is supposed to be readable
anywhere with the simplest of clients - that is its aim, not fancy symbols
and pretty pictures.

About time we got rid of it then and got something up to date.

Slight problem :-(
What do we do with the existing users/programs etc. :-(

Should we get rid of shovels and spades just because we have mechanical
diggers like JCBs?
Horses for courses.... if you want flashy, then go and join a web forum.

There doesn't seem to be any problem when some bossy company wants me
have some new software. They just download it, sometimes without so
much as a by your leave. For instance bloody Adobe automatically goes
on line and does I know not what every time I use Photoshop Elements.

I don't know which is the biggest intrusion in our lives, the damn
government or the damn software companies. I give a false name and
address now every time I'm asked, and if they ask what gender I am I
put hermaphrodite. I bought something on line the other day and they
wanted to know my date of birth! What the **** has that got to do with
them? Can you imagine going into a high street ironmongers to buy a
pair of hinges and being asked when you were born?
