Hi,

I live at zip 43554. According to TVfool.com I am only able to get 1 channel right now, and with my converter box that is all that I'm getting. Converter box is the Zenith DTT901. 2 days ago, I was able to pull 2 other channels with their sub-channels and at that time, according to TVfool.com, that was what I was supposed to be able to get. Why is there a difference in just 2 days? And will this get better after the signals are increased in June?

Also, will the digital signal be affected by the weather? For example, if we have a storm move in, or it gets real foggy, with this kill the DTV reception?

You will need a deep fringe setup most are UHf some VHf
tv fool states 26 channels possible with 4 being Vhf the rest UHf
an indoor antenna is of no use to you. you need a deep fringe antenna setup use the deep fringe prescription in the reception thread you will need all the UHF and VHf antenna the Pre amp and the rotator.:)
use this and with the zenith box you will get marked improvement in your reception this antenna system will need to be at least 20 ft from ground.

Thank you for your reply. I just posted my current set-up to another thread for everyone to review, rather than jam it all in here.

Can you tell me why 2 days ago I was able to pull the PBS channel 27 (with all 4 subchannels) and now it won't come in at all? Today I can get 1 digital channel, 40-1, no matter where I set the antenna.

it depends on many things and an indoor antenna is effected by insulation wiring, overhead duct work metal roofs etc, that is why they are not good for areas with a weal signal. also many of your transmitters are 1 edge and 2edge meaning they are blocked by something. so you need to be able to get higher than the object or shoot over it. also many of the broadcasters are cutting power to work on or tweak their transmitters as they cannot be worked on at high power will fry the worker. so outdoor antennas are the best for these situations they are not affected as much by things.:)

Wow, thanks, I wondered what the 1 edge and 2 edge meant. I do have an antenna on a tower now, here is the set-up I currently have:

I currently have an antenna tower probably about 40 or 50ft high (have to double check the height). It has a UHF antenna mounted on top and below that is a VHF antenna. There is also a signal combiner box and a rotator. (The box inside inside the house says CDE Antenna Rotator, and it is the old "turn the dial type.) There is a Radio Shack high gain signal amplifier (15-2007) also mounted under the antenna.

I'm thinking that I'd like to update the rotor, and get one that has the digital tuning, as it's a real pain to try and get things tuned in for the digital channels. But I'm wonder if the antenna set-up that I have is sufficient, or if I need to look at updating that as well?

Should I ditch the amplifier and go with the preamp instead?

My hubby wondered if we shouldn't look at a whole new antenna set-up.

If need be, I can take a picture of the antenna and post it, if that would help.

Antennas have a life span of about 10 years, they begin to lose signal gathering capacity, if you change anything I would use the 91-xg from antennas direct for the UHF and replace the radio shack pre amp with the channel master titan 7777 this will combine the two antennas and you can lose the combiner which will give a boost in gain of about 3db. you will attach the uhf to the uhf input and the vhf to the vhf input and the have one coax coming from the pre amp to the house.your old VHF should do the trick:) a picture would help to make a good suggestion.

Sorry for the delay, I was away from the computer yesterday. Here's a picture of the set-up.
ok you have two good antennas the channel Master 4228 for UHF and Iam not sure about the VHf, the channel master is good but the 91-xg is better for the fact that you can tilt it 15 degrees to help with the 1 edge 2edge problem I would change the pre amp to a channel master titan 7777 which will combine the two antennas without a combiner and is low noise, noise effects digital more than analog. you can add the channel master programmable rotator if you wish, find it in my deep fringe prescription post 9251a I think but the new pre amp and the 91-xg should solve your problem. also the 4228s are bringing a good price these days since they are not made anymore and are still sought after, so you could resale it.:) PS. when you stack antennas make sure the UHF and the Vhf are at least 4 ft apart or they will interfere with each other.

Thanks for the replies and all the advice! :)

I'm sure that the set-up is old, it was here when I bought the house in 2001, so it's probably invest in the new equipment. We'll go ahead and proceed with the recommendations. I really appreciate all the help!

Just checked the zip on Address and it shows a boat load of analog channels for the area but only two for digital. And both of those are vhf. Antennaweb has very conservative estimates but one would think with all the analog channels available there you could pick up more digitals.
I have to agree, that the estimates are conservative. I know that there are at least 3 more channels that are broadcasting in digital that what is shown on their website.

Tv fool gives the best look she has a boat load of digtials but the are 1 edge 2 edge not LOS so the 8 bay is at a disadvantage because it works best line of sight. where the 91-XG can be tilted to overcome the object much like a SAT dish is tilted to shoot over trees.

I didn't know about the db8 only working good within the line of sight, but from everything I've read on line the 91-XG is indeed the very best UHF antenna on the market hands down.

for those that don't know, the 91-XG is highly directional (as are all yaqis) so an antenna rotator must be used to pick up all distant channels from differnt directions. Also iirc, it's range is estimated to be 70 miles.
