johnmadelz,
I am a beginer of electronics world I would like to ask some
information about antenna that can accept better reception than
dipole antenna.
Your question is too general. What kind of reception are you looking
for, Television? I'm assuming TV, and the problem here is not dipole
vs. some other type but which kind of dipole. Television is either VHF
or UHF, in that US VHF is channels 2 through 12. UHF is the higher
channels. The problem with what we call 'rabbit ears', the little indoor
antennas that sit on top of the set is that they are often cheaply made
and sometimes come with funny little extra things that do little for
reception and only add to the cost.
TV reception is better now than it was in the 'old days'. Stations
have more power, receivers are more sensitive. Sensitivity helps
but the set still needs a strong signal. What makes things worse
is that the dipole is somewhat directional and TV stations are
generally each in a different direction from the antenna. I have
always found that 'rabbit ears' must be adjusted for optimum
results for each station. Better antennas are made but they
usually must be mounted on the roof of the building. That is
partly because they are usually large and bulky. In addition,
the best reception may requires several antennas, each pointed
in a different direction. This depends on how distant the
stations are and how divers their direction.
I know that u know better. this is the reason why I
ask better antenna,Because the place where my house is located is
very far from the transmitter and theres some mountain cover.
Now that is also a problem. The outdoor antennas most often used
for distant reception are called Yagis, they consist of many elements,
that make the antenna more sensitive in one direction than another.
These antennas won't correct for the effect of mountains, but
if you are getting some kind of signal now, they might help. I will
leave the rest of the answer to this problem to someone who has
worked more recently with TV antennas.
