This is a discussion on Cablevision shut off my Fox channel. Need to know how I can receive for sports! within the DTV | HDTV Reception and Antenna Discussion forums, part of the Over-the-Air (Antenna TV) category.
Hi Jack! Welcome to DTV USA.
There is no special antenna needed for HDTV. A TV antenna is a TV antenna and will pick up both analog and digital signals.
Can you go to TV Fool and put in your address, generate a report then copy and paste the resulting web address (URL)? This will give us a report about your location sans your personal data. This way we can recommend an antenna for you.

Assuming your in New York City, WNYN is broadcast on RF channel 44 which is in the UHF band. (My9 WWOR is broadcast on RF channel 38) You will need a UHF antenna for those channels. Both are broadcast from the Empire State Building. That is the direction you will need to point your antenna. You can get more detailed info from TVfool. Depending on where you are with relation to the broadcast towers will determine how powerful of antenna you may need. Attached is a picture of a simple UHF antenna that I've built that I've used to pull in signals from 49 miles away.Get Free HDTV.jpg

Long ago (back in the CB radio days-1960s/70s) I participated in many 'rabbit-hunts' where one in our group would drive somewhere and hide: it was our job to find the rabbit using loop antennas. I still have my HF loop which has the ability to be tuned to resonance for different bands.
The reflector you added is 90 degrees off to the side of your loops' main lobes or focal points. Loops are highly bi-directional and they receive signals on the side like this--> | ... not like this--> O Your reflector is blocking signals on one side of the antennas' design null and encouraging or reflecting signals from the opposite side of the antenna, also a design null.
In theory, the reflector you added shouldn't be helping at all (except additional blocking from one direction). Have you tried your loop without the reflector present? I bet you get the same reception without it.
If you take a look in my photo albums you will find an altered loop I built and tested summer before last. Its reception behavior at UHF frequencies was unpredictable compared to my low-band experience. My best guess is the balun itself needed to be shielded (put inside a grounded project box) to keep it from contributing as an antenna. The same is probably true for your setup.
I did a bunch of loop antenna research two years ago and I cannot recall anyone trying to incorporate a reflector with a loop antenna. On the other hand, if it works for you, that's great! OTA reception can be a black art and experimentation goes a long way.

It may be a bumble bee, but I've found that the reflector adds about 20% signal strength based on my RCA DTA800. The RCA DTA800 seems to have a pure signal strength meter on it.
Oh yeah, and what is a Antennas Direct C series antenna other than loop antennas with a reflector?

Only thing I have to say about sports is, I hate sports, I wish sports were illegal. It is a total waste of money for tax payers to spend money on sports in the school system. Schools are for education and sports has nothing to do with education. I finally got the point across all the new schools in town have no sports, no gym, no soccer or ball field, no coach. 4 new schools with no sports saved the tax payers a lot of money. Everyone is looking for ways to save money the only thing people understand these days are dollar signs $$$$$$$$$.
But given the high level of obesity and low levels of activity amongst our population, I believe we need physical education in schools. And not the "Dodge ball" type, jock - dominated, team sports oriented program I suffered through as a student, but a program that will teach physical activities that can be enjoyed throughout a life time.
After all, when was the last time you got together a bunch of people for a game of dodge ball or football? Hey, half of all the jocks in my senior class are lard asses 30 years later. Just sayin'...

The chance to play football was one of the things I enjoyed most about my small High School experience. Lot's of kids don't get that opportunity because they go to large schools where you have to "make the team." Being able to play in High School is why I watched Nebraska beat OSU, and the Raiders cream the Broncos this weekend. To a limited degree I can relate.
