Installing 7.5 bud

[dl76]

Ok guys i am gonna install the dish on my pole today. I am going to have some question in the process. i will keep all my questions and progress in this one thread. Thanks in advanced to anyone who helps.

My first couple of question are . Can i use the same scalar ring that came with the dish with the new C1W-PLL lite lnb?
Next question is can i use the same focal depth as the old one used? if so what would be the focal depth be on this old one? Also what focal depth should i set it at on the new lnb? pic below


Also does the dielectric slab need to be installed? if so how is it installed inside lnb?

I would use the Scalar ring that came with the dish as it is designed for that dish, and is beefier.
If the focal depth has not been touched since the dish last worked, the new one should go about in the same place.
No on the Di-electric slab, that is only used for circular reception. Don't know how far east you can see, but the satellites over NA are all linear and not circular.

I wouldn't assume that the last installer set the scalar or feedhorn correctly. Fixed many installs that were installed wrong and the customer had no idea for years!

Have fun!

Thanks Titanium . I found link as soon after i posted. Guess i should had searched first. Also thanks for the fast shipping on lnb. The dish came not even a mile down the road. So hopefully everything was set right. Just got it up on post.

Your getting closer!!

 

[bpalone]

You should be able to get a picture from it before to long. Then the finer art stuff kicks in and sometimes kicks one's behind. Since it came from close by, should go pretty easy, assuming it was set well to begin with.

Have fun.

Well the superjack motor thats on it is froze up. Tested with car battery and dosent work. Check for voltage inside actuactor motor and getting 12 volts. Had a grease point and i greased it also. I got 4 other actuators. They all worked with battery test.

Well guys. I changed out actuators. It raised it up a good bit from where it was at from orginal place it was at about a mile down road . I think the the actuator on it was an 18 inch. And i think i put a 24 inch on it. Does it matter what size actuator and dish sizes?

Longer actuator is better,will give it more travel.Just make sure it doesn't push so far that it starts binding up or flops over.In other words,you may have to re-set the limit lower if necessary.
My 7.5 has a 24 inch actuator already...and I wish it was longer.YMMV

There are some older threads here that explain how to adjust the bracket holding the actuator.Basically you retract the actuator all the way in,then position the bracket for the lowest satellite on that side.(With a little bit of extra play for fine tuning) That way you get the most 'forward' reach possible.

You will need to re-align the dish on true south again regardless.Maximum height/position on the dish will now be different than before.

More experienced members can explain it better if needed.

Thanks armadillo_115. I will do some more reading. I actually have all 3 size actuators. I got one called a hammerblow. And it has to be a 36 inch. Its the longest one i got. I will work on it more tomorrow. You guys have a great evening. Gonna watch my clemson tigers hopefully win tonight..

I wish you the best of luck, dl76.
There are some great guys here in this forum who will help you along as needed.I'm still in satellite pre-school myself.

Will i have to adjust the elevation on the dish? Also if my Longitude 81.1538° my true south satellite should be 82 west correct?
Confused on what to do first. Not sure if elevation is thrown off now with using a bigger actuator. Not sure where to start first. i assume retract the actuator all the way in,then position the bracket for the lowest satellite on that side which would be 139 west .

Instead of typing a lot, I'll let you look over my BUD manual @ http://www.wisegise.net/BUD/ Install is left to right on the top line then the bottom line of the page links (Hey, I recently spell checked most of the pages)
Yeah, 82W is the closest to south satellite.

I'd check satellite elevations of 139W to what you can see to the east. www.dishpointer.com
If the furthest east satellite you can see is closer to the horizon (lower) than 139W I'd move the actuator onto the east side of the pole.
replacing the actuator alone will not change your elevation setting. Nor your declination. Nor your mount azimuth.

I stand corrected.Mount azimuth remains the same regardless of the actuator length. Dish will have to be re-aligned/peaked though because it is a new set-up.Thanks for catching that Fat Air.

At least that's what I THINK I mean.lol.Not sure if I have just a sinus infection or the start of the flu...but my head feels like it has enough cement in it to plant a small dish.

What am I missing here? I thought the furthest eastern satellite for most of the US was 72 West? Someone please explain?
How stupid am I - someone please explain?

 

[Titanium]

Depends where you live in the US. If living on the East coast and a view to the eastern horizon, you would see down to about 10w or some even lower. Many European satellites do not have CONUS footprints, but several do have several global or North America targeted transponders.

Living in Northern California, many members can see down to 55w to the East and 169e (equivalent 191w) on the Western side.

FaT Air is saying to see Which is lowest to the horizon, the western-most satellite that you will see OR the eastern-most satellite that you will see - from your location.
Example: At my location - 139W is closest to the horizon on my west side. Due to the hill east of my house - 61W is the closest to the horizon that I can see. My true south satellite is 82W, so I can see 57 deg to the west from my true south - the true south is the highest point in the sky that your dish will point towards. I can only see 21 degrees east of my true south - due to the hill which blocks satellites further east.
Therefore, by FaT Air's advice, I would put my actuator on the west side of my pole - which is exactly where it is. It points just below 139W when Fully Retracted.

 

[FaT Air]

Clarification: which ever is at a lower elevation, furthest E or W, is the side one should put the actuator.
Example: Can see 139W, at 21.6° Elevation. All the way over to 30W, at 6.4° elevation.
Actuator is on the east. (although, in my case, I'm limited to 55W by mechanical limitations of the polar mount. Which I'm dreaming about correcting)
55W & 58W are 'nice ones to have' if you can get 'em.
EDIT: Yeah, last satellite azimuth works out the same > whichever side is the greatest azimuth from center would be the side for the actuator.

Thought i would give an update. After work today. I tightened the actuator on dish. Its a 24 inch venture. After i retracted the motor it almost put it back in same spot as the 18 inch super jack that is bad. Anyways. I am assuming i can use this pansat 1500 to align this dish.

If you haven't done this already, do it. It will make the rest of the job way easier. Run the dish up to its highest point, where going either direction decreases the elevation. Then do your absolute best at getting it pointed DUE SOUTH (True), then snug the dish to the pole just tight enough that it doesn't move on its own. That alone usually makes the rest of the job a cake walk.

Now pick a known good active transponder on your satellite closest to due south, tune to it on your receiver and start bumping the dish the proper direction. If the declination and elevation are correct it should pop right in. Then due the normal push and pulls to peak it, along with some minor adjustments. then start walking from satellite to satellite making note of the count, etc. until you are either at the end of the arc that direction or you can't find the next one on your list. Might want to do a little push and pull while on the last one to which way you are off and make note of it. Then go back to the peak and start down the other side, doing the same thing.

If you nailed Due South, you probably won't have to do much more. Just the finer tuning things everyone does to squeeze a bit more out.

Good luck and above all, have fun.
