8 west inclined/declined orbit

[martin-f]

hi
i have had a dish given me its a 800x700 i have it pointed at 8 west all working fine. i am wanting to pick up the inclined/declined orbit on this bird for footy i have 2 lnb and a bracket could i use both lnb so i keep a lock on both inclined/declined ?
and also how many degrees would i have to raise/lower the dish to get a lock also is there any tp's to lock onto that can be found at any time thanks in advance for any info

Its 3.5 degrees inclined which is a hell of an inclination. Its doing a figure of 8 every day passing through the middle of the 8 twice a day as it wobbles up and down

The only way to track it properly is with a motorised 2 axis dish

thanks for the info AS is there only feeds on this bird is there any tp to use to lock on to it or is it just a case of watching for a feed posted then trying to lock on thanks again for any info

Sorry dont know - 8W is just about behind a tree here so I rarely bother with that bit of the arc as I have to set up a dish specifically to get it. Just outside the front door as well which makes getting in and out of the house hazardous....!

A dish with two lnb's mounted one above the other to watch an inclined bird is an interesting idea - Ive never heard of it being done. You would lose the signal in the transition period between the two outer nodes of the orbit, but might be worth trying as an experiment!

thanks AS i will have a play tomorrow there is usually some feeds posted on saturdays i will post the results with 2 lnb if any
silly question ? do i raise the lnb towards the sky or lower it to the floor i do not know if it works the opposite way round thanks

Err lats see - it wont be mirror image this time - the top lobe of the loop will require the lnb to be higher than the usual arc plane

If you check here:

LIVE REAL TIME SATELLITE TRACKING AND PREDICTIONS: TELECOM 2D

and set the upper lnb up when Telecom 2D is near latitude +3.5 you can then wait a few hours until shes down at latitude -3.5 to test the lower lnb

Or vice versa if shes well down in -ve latitude when you start!

thanks again AS i will have a play tomorrow

i have dropped the dish around -3.5 and picking up a fair few feeds most are 4.2.2 so i now will have to work it so i can scan with the tm 1500 then move to my azbox to view them just scanning now and picking up 10 feeds so quite good i will ad the other lnb when i know if the bird is rising are falling thanks for your help AS

No problem matey --> Telecom 2D was at +3.4 about 2300 uk time last night. I think we need a photo of the over/under lnb system when its complete

To switch between the 2 receivers get an A/B switch - about a tenner on fleabay.

If it works might be worth submitting it to Alex the editor at Wotsat - they are always looking for interesting projects to feature on the blog or in the magazine

thanks AS i have a 4-way diseqc switch here will that do the trick it has lnb 1to4 and a out on it i am using 2 dishes one motorised and this one on 8 west
some pics here of what i am tring to do the bottom lnb has a lock atm i am going to leave the cable on the top lnb an scan later on i think a bit of playing around should do it i hope i will keep you posted if i get anywhere its to cold now to play
