S band digital HD LNBF
S band digital HD LNBF
Well though I would ask. Am planning on getting a KU band to add to my C band LNB. Came across this S band. Any comments on this LNB for North America?
Spec.
Input Frequency: 2.3 to 2.7Ghz, 2.2 to2.7Ghz, 2.5 to 2.9Ghz, 2.3 to 2.9Ghz
L.O. Frequency: 3650,3750,3850,3950MHz
Output Frequency:950 to 1350 MHz, 1050 to 1550 MHz, 1050 to 1650 MHz
L.O. Stability: 1.5MHz(-40to+70/25)
Noise Figure:0.4DbConversion
gain:50dB

Re: S band digital HD LNBF
So S-band is used for radio transmissions like Sirius XM? Anything FTA worth adding to our satellite charts? If so, I could look into it.

Re: S band digital HD LNBF
Well did a little reading and seem that Asia seem to be using S band.

Hope I'm not in trouble by posting live links.The last link show a S band set up. The language is not English but there seem to be a use out there other then radio transmissions for S band.Not sure if it needs a better look at.Not sure if there is any FTA channels using S band.

Buzzie,
The PDF file is what I was referring to above...... the bottom
3 pictures represent my most recent attempt at S band.
Most of the activity on S band that I've found is at a much lower
frequency band. typically 1900 - 2400 MHZ. Most of this is Amateur
Radio Satellites. But there is quite a lot of stuff in this range.
If you Google S band space craft you'll find quite a bit.

Very nice, foxcreek!
Are those parasitic (director) elements in the focal region of the reflector? I see one active (driven) element in your primary feed...

elko,
Yep that's a 14 element Yagi ( 12 directors, 1 reflector, 1 driven element )
Designed for WI - MAX ( 2.5 - 2.7 Ghz. ) 18.0 dB gain. Combined with the
30 inch dish about 40 dB gain total not counting the gain of the downconverter
( Drake MMDS band ) .
This of course is all analog so all those digital signals out there sound like buzzer's
on an AM detector !

ALL,
Here's a Link to S band satellites: http://www.zarya.info/Frequencies/FrequenciesSband.php

Re: S band digital HD LNBF
What is the purpose of director and reflector elements in an antenna design based on a signal convergence point? Shouldn't a single driven element be placed at the focal point?
What is the performance when placing a director element at the convergence point vs a single driven element or a driven/reflector?
