Increasing Satellite Signal Quality

[cyberham]

If you have nothing to do, take a look at this video: Click here

The video shows an individual increasing the length of the small antennas inside an LNB. His purpose for this modification is to improve the LNB's ability to receive higher quality satellite signals. I'm not sure I believe this video.

Lengthening the antennas possibly will increase the signal level...but will it increase the signal-to-noise ratio which is what counts? After all, noise will also increase when using a longer antenna. He increases antenna length from maybe a little less than 1 cm to about 1.5 cm. Is this small change going to have any real effect? If it was this simple, then why wouldn't manufacturers simply install longer antennas (easy at the manufacturing stage) to improve performance?

Do you believe this video?

IF that worked, the companies that produce them would do it from the start.

The antenna length is tuned to a specific frequency range. Altering the length might dial a specific frequency in better if he knows what he's doing or at least gets lucky. Lengthening the antenna in hopes of grabbing more signal doesn't work unless the length is a multiple of the base frequency which wouldn't fit in the LNB housing. A larger reflector is needed to capture more signal assuming everything is dialed in correctly.
