Default Added rotor - now fewer channels

Hi there
I have added a rotor to my setup.
Setup is:
DB8 antenna
CM7777 amp - mounted above rotor
CM rotor
All mounted on a 10' length of galvanized pipe attached to my chimney.
Approx 6' of pipe to rotor then 4' above with amp and antenna
Puts the antenna at about 30'
Prior to the rotor addition with the antenna aimed at around 210 degrees I was getting 19 HD channels.
Now with the rotor I cannot find any one direction that provides more than 12 channels and I specifically can't find 2.1, 2.1, 2.3, 9, 51.1, 51.2,51.3
Have I screwed something up?
Thanks for any advice.
K

Not sure what to say KMAG. You are between me and 2-1 I get it reliably. So how is 4-1, 7-1 signal power? They should be 100% 9-1 is not surprising as they are low power until the changeover. Analogue 9 should be no issue. 51-1 is trickier as it lies ½ way between Buffalo and Rochester as the antenna points and the signal is directional not in our direction. Depending on weather it drops out here periodically. 12 channels per position (normal to me) is a fair trade of for reliability as no rotor means compromise positioning.What is the cable run like with what kind of quality parts? Did you do a complete rescan after install or are you searching manually?

Default Failed Rotor Controller

I figured it out. There was actually a problem with The controller. While it synchronized correctly at first, something went wrong so that the antenna was not pointing in the direction displayed on the controller. The vendor replaced the controller for me and everything is working correctly. I've actually gained a channel. Now 21 digital and 11 analog. Quite happy. Thanks.

Default CM4228 question?

I am looking at my antenna options.

The CM4228HD is rated at:

60 miles uhf
45 miles VHF

my tv fool says Rochester,NY is 83.5 miles SSE,167 deg. true north.

http://www.tvfool.com/?option=com_wr...3cf46d22dd7a92

Is anybody (the closer the better)getting Rochester,NY with it and a cm7777 preamp?

While we're at it...

Will I have problems with 18 and 44 analog @15.8 miles and 27 Global @19.0 miles overloadin g the amp and Sony Bravia KDL46SL140 's tuner?

btw: I'd like to avoid a rotor ,if poss.

I was thinking:

ch. 7-13 ant. pointed at Rochester,NY
cm4228HD(or other) aimed South?

+ preamp

suggestions?

btw: Just researching right now.This is a Spring project.If it works,I'll shut Shawdirect off for 6 months and think about telling them where to go! lol

ITpro007 I am at the west end of the lake, so pretty close to you. Yes I know they claim it does but I was not confident that model does well on HI VHF at fringe distances (Anyone seen some gain charts for this?) Look at all the other antennas that are of similar design. How many of them say 14-69? So if true, 45 miles VHF is way below what U need anyway. Rochester is hard to get here, low height transmitters, some signals directional. It was 10 & 13 that made me change my mind and get 2 separate antennas. You need a powerful VHF and UHF or all channel fringe style unit. Look around at your neighbors towers for E.G. You may need to trap those strong channels. No rotor will seriously cut your channel lineup. Not sure where your antenna should point but Rochester is south of you. More stuff towards Buffalo. Better choice with no rotor.

Thanls Wilspin,I will keep those thoughts in mind.

I decided I'm going to grab a CM4228HD in the next month and go from there.

Yes,I think you\re right.Rochester VHF-hi will require anothe ant. ie: Antennacraft 10 el. ch. 7-13.

Look around at my neighbor's towers?

They're all from the Stone Age!

No UHF,legs bent,or falling off....

I should imagine a lot have Cable and some have Satellite.

Anyway,we'll see how she goes.

I'll mount it on the side of the tv tower just above roof level,proabbly facing SW.

From here:

Rochester= 83.3 miles,167 deg. SSE

Harwood=15.x miles 214 deg,ssw
Baltimore=19.0 miles,209 deg. .ssw -ch. 27,Global

btw: did put an original Antennacraft 4 bay bowtie up yrs ago,but not knowing anything,fed it with twin lead.Terrible signal.Went to recently replace it with coax.All rusted out!Couldn't evern budge the wing nuts -live and learn! lol

Even the ones from the Stone Age will still work. They will also indicate what type of equipment you need to get quality reception. lots 'o' big long ones?

There are some combo antennas,but most are vhf only.Big suckers,probably Delhi Crossfires,or such like.10,12 ft. booms,I figure.

btw: I see by your signature(as all OTA pros do),you have a separate vhf ant.

I'm figuring on an Antennacraft 10 el 7-13 ant. for Rochester.Plus,something else for 21(16) and 31(38),8(45).

Oops sorry Stampeder! You will find 21 and 31 (28) a challenge to get reliably.
