The comparison was conducted on my motorized (SG2100) 36" Azure Shine dish and my Pansat 3500.

I read on the forums that the frequency's detected by this LNB are not very accurate,
but I found the frequencies to be the same as my Lava LNB which gives very accurate frequency readings.

All the LNBs except the Tele-Comm T-1500 were able to fit the standard LNB holder.
I tried a larger holder (For a C-Band LNB) for the Tele-Comm T-1500 but it was to large to fit the LNB, but that was not going to stop me
So I had to find three of man's best friends. (Not dogs ) Duct Tape, Tie Wraps, and a F-Connector (Normally used as a connector for RG-6 coaxial cables)
I duct taped the f-connector to the end of the satellite dish's LNB arm, placed the Tele-Comm T-1500 LNB on top (moved the LNB around to find the correct focal point), and tie wrapped it in place.

Images to fit the Tele-Comm T-1500 LNB to my 36" dish are attached below.

Test time was around 5:00 PM PST on Saturday, December 29, 2007.
The weather was: clear skys, no wind, and a cold 40°Fahrenheit.

My Final Opinion:
The Tele-Comm T-1500 sold by Sadoun is a very low priced LNB, at $9 I am very surprised that it ranks second place against much higher priced LNBs.
If price is a factor and you do not mind making your own mount (Or finding one), the Tele-Comm T-1500 is a amazing deal at only $9 before shipping and tax.

Thank you Sadoun for allowing me to review this LNB. (This is my first review so I hope I got everything in here )
All prices are before shipping and tax. (12/31/07)

very nice review...love the duct tape job

I'm kinda shocked at the numbers it put up...but then again, the red LNB I have kinda did the same

Thanks for the Review qwert! I think you did an excellent job on your review. Now, just to put my mind at ease and make sure we are on the same page, the Invacom is the Winner here, correct?
