Greetings to All,
I'm a new member.I live on the south shore of Montreal.
I've consulted tvfool.com to see what is possible for me to get in my region
I have a Zenith dtt901 converter
I have built a single bay and a double bay bowtie antenna.
Its about 20 feet high and i have a tall maple tree that may be interfering a bit ...
Oddly enough I only get about 5% better signal with my double bay bowtie antenna compared to my single bay which is disappointing but the signal does vary less ; instead of varying 40% it now varies only 15% which is good.
I've gotten good results so far but it could be better:
I get all local stations well: 60-80% signal.
I also get 2 out of 6 USA stations good 50-75% , 2 are borderline 35%-50% and the other 2 stations are from 0 to 33%
i would really like to get the 4 weaker US stations that are about the same distance and direction but are a bit more difficult to pull in.
One is channel 13 which probably has a lower gain being in the low spectrum of the bandwidth ...
I'm trying to see if my existing setup could be modified to get better reception
-Instead of placing the balun exactly in the middle between the the 2nd and 3rd bowtie i put it on the 3rd bowtie directly.Would that make a practical difference? Also when I combined both antennas side by side I placed the balun on the left antenna on the 3rd bowtie directly instead of in the middle between both antenna again, Would that make a practical difference?
I've seen 2 types of plans for the bowtie antenna :
-In one the V shape is 7 inches and in the other plan has it is 8 inches long a 1 inch difference. What does this affect ?
-Both plans have about 2 1/4 " distance between the tips of the V's vertically but One plan has the bowtie 5" open instead of 3 " therefore the vertical spacing of the V's are 7 inches apart instead of my 5 3/4" apart.
What does this affect ?
-I'm now going to build the Hoverman single bay antenna. I noticed it has 6 V shapes instead of the 8 V's of the bowtie antenna yet it's been said to have a better gain than the bowtie antenna. True ? Why ?
-The double bay Hoverman is said to have a 100 mile range compared to the double bay bowtie antenna which is said to have a 65 mile range yet it has 4 extra V's True ?
-I have about 20 feet of cable from the roof to the inside my house then about 45 feet of cable to reach my TV would a preamp at the antenna help much ? what would be my gain typically 15% ? or maybe an amp after my first 20 feet of cable ?
I've been reading a lot but can't seem find answers to my questions so if anyone can help I would appreciate it
