Default TV Antenna.....Please Help....

You would probably need to replace the twinlead as well as the antenna.
The next time you see a Radio shack, you might sneak inside and ask about TV
antennas.
Or they probably have a web site. with prices
Yeah - they do - click on this link...

All,
Some History...
My home, previously owned by my parents, has approximately a 30' Tower


I liked the range of the previous antenna, so what would everyone
suggest for an antenna with a range of around 100-125 miles that could
be mounted to a 30 foot tower and will be used for radio and TV
reception I have made a few phone calls and everyone locally pushes
the Channel Master but I am little nervous about having to have to do
this every 7-10 years based on the last antenna. Has anyone had better
experience with Channel Master?

As its been used like three times, would you replace the rotor motor?

What should I expect to pay to have a new antenna and rotor motor
installed in my home?

Anyone know a good antenna dealer in the Toledo, Ohio area?

Thanks,
Chris

Firstly ,it is my understanding that in the USA all terrestrial TV
stations will go digital in 2009 , so it would be useful to know which
are the frequencies/bands this service will be offered in your (Toledo)
area ,before you buy any new antenna.

Secondly ,most ,if not all TV sets nowadays have an antenna input socket
for 75 Ohms coax. Since coax is less 'environment sensitive' than twin
lead feeder , it does make sense to run coax to the antenna.
If the antenna's active element is a folded dipole ,its connection box
will include a (usually pig nose type) 4:1 balun.

Give twinlead a twist every couple of feet and you save the cost of that
coax.
At the freqs used, most coax could be rather lossy, depending on the length
of the run, but twinlead has a very happy combination of being low-loss -
and - low-cost compared to most coax. (And lighter weight too.)
The 4-1 balun ( coax to twinlead adapter) is cheap enough.
I've used twinlead and tv baluns for a 200-ft run to my antenna on 10 meters
(5 watts) with good results both tx and rec.
Ya just gotta match impedences and you're good to go.

When it's new, when it's clean, and when it's dry.

As I understand it, one of the bigger downfalls of ordinary 300-ohm
twinlead for TV reception is that its performance can deteriorate
rather badly with age. Sunlight causes the PVC to deteriorate, and
surface contamination and moisture (e.g. rain) can significantly
increase the losses.

Coax is much less vulnerable to these problems.

It's also subject to problems if it is too close to things, remember those
special standoff insulators for it? It can not be looped, wrapped around things,
etc.

All,
I think the antenna has a coax connection built into it (One of
advertisements I saw). Also the previous wire was coax as is the rest
of the house. So I think Coax is a given for me due to simplicity and
never having any problems with it in the past. I will keep it in mind
though if something would change on the antenna or plans.

Thanks again,
Chris
