Can I use a legacy lnb to "just" tune in a T-90 dish"?

[rhino1616]

I have a bunch of dual outputDN legacy lnb's hanging around & I have a viewsat palt w/ T-90 dish ( i dont want to spend the money to buy a bunch of reverse polarity lnb's)
. I've read that you can use regular lnb's, but you have to reverse the polarity settings in ird settings. my question is do I have to first put on a reverse lnb find the sat, scan it, then go to ird & reverse the polarity's, or can I directly add the DN lnb & tune into the sat & then go to the IRD & reverse the polarity. I dont want to go on the roof & stay thier for a hour trying to tune into a sat only to later realize that the DN lnb wont even pick up the signal because its not a reverse lnb. can I at least tune into a sat with this lnb & later reverse the polarity or will it not even see/recognize the signal?
Thank you

PS: my apologize if I posted in the rong forumn, I "THINK" this is the correct forumn.

Yep, you can use legacy just fine.

for NASA & Angel One yeah that works just fine

Using a regular LNBF, reverse the polarity (from what the different satellite charts indicate) before you try to align the dish or find the signal. It is the extra reflection that causes the polarity to be reversed, so you change the polarity settings in the receiver to be opposite of what is listed and you will be good to go searching fo a signal.
Don't forget to select an active transponder, or you will never find a signal.

That's how I got my T90 set up at the beginning. I'd put an LNB at 82W, and one at 110 or 119, which ever happened to be at the opposite end of the rail, and I'd pretty much have my skew.

Just remember that you'll still have to tweak. Those sats are so strong that a linear one may still be pretty weak without tweaking.
