[sci.electronics] New antenna?

michael1@ihlpf.ATT.COM (00704a-Pula) (02/18/88)

   Hi, I've got a question that hopefully someone can set me straight on.

   My folks have been getting crummy reception on 2 of their 4 TV sets.
   Their antenna (outdoor chimmney mount) is 20+ years old.  Last year
   They asked me to wire the house for complete antenna hook up and VCR
   compatability.  So it goes something like this:

   
                                         |---------  TV 1
                      -------            |---------  TV 2
   outdoor antenna -->| VCR |----------->|---------  TV 3
                      -------            |---------  TV 4

   appropriate UHF & VHF splitters have been used and a good quality cable
   also.  BTW, splitter is one of those Radio Schlock distribution amplifier
   types.

   QUESTIONS:
   1). Is this a big NO-NO?
   2). Is the antenna too old or weak to pull in signals?
   3). Are cable runs too far?  
   4). Any recommendations on a good antenna?
   5). Any other relevant comments?  suggestions?


Thanks in advance,
Mike

After 20 years, corrosion where the elements connect electrically has
probably adversely affected the antenna. A new one is probably called for.

You don't say if you used coax or twin-lead, or the length of the runs.
In a normal house, you shouldn't have to worry about length of runs using
coax.

Depends on TV station signal strength and transmitter locations in the area.

Your setup with the VCR upstream of the TV sets means that if the VCR is
playing, nobody can watch anything else at the same time.
