Have fun explaining why it was virtually impossible to get a picture
without the MHA. There is a difference between a mast head amp and a
distribution amp as used in blocks of flats in case you didn't know.

** Do not believe this LIAR.

His claims are deliberately false and / or missing crucial details.

MHA are not of any use with such short cable runs.

No there isnt on how they work in poor signal areas.

If there is fuck all signal at that antenna connector,
no mast head amp will do a damned thing about that.

If the signal at the antenna connector is barely adequate,
a mast head amp does avoid any loss at all in the cable
and that can see an adequate signal at the TV etc.

That's why you see that effect with a mast head amp in poor signal areas.

Generally no.

External antennae a usually placed in a high position clear of line of
sight obstructions. As well, they have a much higher gain factor and you
can see this by the number of elements on them. The rabbit ears are a
basic dipole antenna and will have two active elements only. A
directional external antena will have the two active elements plus a
variable number of director and reflector elements. Director elements
are progressively shorter whilst reflector elements are progressively
longer than the active elements. Directional antennae, like those on the
rooves of houses everywhere, provide much more signal gain.

Normally not. Only a subset have mast head amps.

That's a large part of it.

Nope.


Yep, they arent using what signal does get into the house
past the foil insulation that's often in the walls etc.

And they are much bigger than most want in their house
too and can be designed to work best at the frequencys
that the TV broadcasts are on.

Even a pure UHF external antenna isnt that small and
bigger than most want inside their living room etc.

Sometimes they are, sometimes they arent.

Its just not possible in some places.

no. maybe you are closer to their transmitters, or their frequencies are
being received better

Quoted text here. Click to load it

the longer the better

Quoted text here. Click to load it

normally it only amplifies what is being received, unless it's a more
sophisticated kind that filters the noise and boosts the signal

Quoted text here. Click to load it

no, but you can use a powered mast head amplifier that requires DC
voltage up the antenna cable

put it up as high as possible, and you could use something like this..

generally the best solution is to use an external antenna, even a small
one just mounted on the gutter, or in the ceiling unless you have an
iron roof, is better than an internal antenna where the signal has to go
thru walls, etc.

He did later, and those usually donít do analog.

Sure, but it doesnít do that filters the noise stuff.

Is keep out the CB and phone bands and that wont be his problem.

Nope.


It does make a difference with the older VHF channels.

Quoted text here. Click to load it

That gets complicated. It doesn't help if there is a lack
of signal where the antenna is, most obviously inside with
either metal walls or that metal insulation in the walls.

It can be useful when the problem is just a pathetically
inadequate antenna supplied with a tiny tuner.

Quoted text here. Click to load it

They can be done either way. They can be entirely passive,
no electricity required, or they can have a mast head amp
at the antenna and that does need power. That's normally
supplied down the coax to the external antenna, with a
device that allows the power to be connected to the coax
at the tuner end of the coax.

Try some of the better internal antennas.

Unfortunately Dick Smith no longer has their 14 day
free trial and return if you don't like it approach, but
BigW still does and likely Kmart etc does.

Bunnings does too, but doesn't have much of a range of them.

You cant specify them that way with the new digital channels.

Worth trying but  not worth buying on the off chance it will help.

A proper external antenna will be better, but rather more expensive.

Plenty do find that a decent internal antenna does work fine with digital
TV.
