Rotorless install
Hi,
I have a friend with the following profile: http://www.tvfool.com/?option=com_wr...f1f08f9f58f660 He would like to get all of the 'major' channels here in Canada but DOES NOT want a rotor. Looking at this report I said he can realistically receive: CJOH-TV (6) to WWTI-DT (21 (50.1) I believe he can pick up: CJOH-TV CICO_DT CIII-DT (27.1) CKWS-DT (11.1) CHEX-DT (12.1) CIII-TV 2 via a omindirectional antenna like a: Channel Master CM3000 Then he will need a long range multibay antenna to pick up: WWNY-TV (97°) WHEC (188°) WHAM (188°) WPBS (101°) WWTI (100°) We are thinking of a: ANTENNAS DIRECT DB8E With one bay pointed at the 97~101° direction And another bay pointed at the 188° direction Is this possible? Can he combine signal and then run it through a pre-amp? |

http://forum.tvfool.com/attachment.p...1&d=1433184279 I am always amazed when someone wants a simple system that duplicates what a CATV system does with multiple antennas, amplifiers, and modulators costing thousands of dollars. You will need to cut back on your expectations and settle for improving one direction or be prepared to spend a lot of time and money building a system that does what you want. Quote:

In spite of some glowing reviews, the antenna with two panels, each aimed in a different direction, often doesn't work. When the same signals from each antenna panel reach the combining point, they can interfere with each other if they are not in phase. Quote:

Follow up questions.
So what could he realistically expect with:
-CM3000 -DB8e with one bay pointed at: at the 97~101° direction -the second bay pointed at: 188° direction -preamp on the DB8e Preamp signal of DB8e + CM signal combined and ran into the home to one tv And to clarify the expectation, we are not expecting to pick up EVERY channel like a CATV tower but the feasibility of picking up: CJOH-TV (6) to WWTI-DT (21 (50.1) -10.3 db |

I suggest starting small with just the most important channels, and build on that. For example, he has 3 CBC: real channel 11, CKWS real channel 30, CKWS real channel 12, CHEX does he really need all three? |

Another example, he has 2 Global:
real channel 27, CIII-DT real channel 2, CIII-TV Antennas for channel 2 are very large, because it is the lowest VHF-Low frequency. Channel 2 is 54 to 60 MHz, center frequency 57 MHz. A simple dipole antenna for channel 2 would be 5540/57 = 97.2 inches or about 8.1 feet long. http://www.channelmaster.com/Digital..._p/cm-3018.htm http://www.channelmaster.com/Digital..._p/cm-3020.htm http://www.channelmaster.com/Masterp..._p/cm-5018.htm http://www.channelmaster.com/Masterp..._p/cm-5020.htm http://www.solidsignal.com/pview.asp?p=hd7084 http://www.solidsignal.com/pview.asp?p=hd8200u The above antennas also receive VHF-High and UHF. Does he really need both? For CTV the only one that is strong enough is CJOH-TV on real channel 6, which is so strong that he could probably receive it with an indoor rabbit ears antenna or folded dipole antenna. 5540/85 = 65 inches, See Attachment So, now we have it down to this for the locals: For CTV, CJOH-TV, real channel 6, an indoor or attic antenna For TVO, CICO-DT, real channel 26, a DB4E in the attic or an RCA ANT751 outside aimed at 45 degrees magnetic For GTN and CBC, CIII-DT real channel 27, and CKWS-DT real channel 30, a DB4E outside aimed at 270 degrees magnetic. A preamp might be needed for this antenna. You can combine the CTV antenna with the TVO antenna with a UVSJ. You might be able to combine the two UHF antennas with a splitter in reverse. I can't guarantee that this will work, but it is my best guess based on my experience, your tvfool report, and what you have told us. |
I live in Belleville and we have two Super Stealth Hawk antennas and a 60 inch dipole for channel 6 CJOH (check DigitalHome.ca) in our attic. The dipole and one SSH are connected to a RCA TVPRAMP1R amp.
Because of the closeness of the two SSH antennas we get CJOH, CKWS and TVO (very strong signal) on the north antenna/TV and CJOH, TVO and Global on the south antenna/TV. We don't get CHEX. Channel 11 CKWS (Wolfe Island - east) comes in strong but pixelates sometimes. Channel 30 CKWS (Brighton - west) comes in strong. CJOH comes in with some noise on both TVs, but it is better than the poor signal the local cable company gave us before we left them in January. Global comes in strong on the south TV. TVO is solid, I've used a paper clip to get it. During Tropo effects we get stations from Watertown, Rochester and Buffalo. I've seen several Channel Master 4228HD's around town. One fixed to face west (CBC & Global), two on rotors facing east/Watertown. I am working on either a Stealth Hawk (single unit) or a Tube version of the Bowtie antenna (after Bouval's 4 bay on DigitalHome) to go on our chimney to face Rochester. FYI - On August 31 CKWS and CHEX will become CTV affiliates. So we lose CBC and get CTV in pure digital. Though I'll miss it, we weren't watching much CBC. David |
Greenish Apple:
Thanks for the update. You know much better than I do what's going on up there. CanadianOTA: Quote:
WWNY-TV (97°), real channel 7 WHEC (188°), real channel 10 WHAM (188°), real channel 13 WPBS (101°), real channel 41 WWTI (100°), real channel 21 You would need a VHF/UHF combo antenna (like the Winegard HD7694P or 7697P) aimed at 100° and a VHF or VHF/UHF combo (because VHF only antennas are getting scarce) antenna aimed at 188°. |
