VIP 622 modulator output levels ??

I posted those numbers a while ago. You may want to do a search. If I find them, I'll post them again.

Awesome! Thanks a bunch.

Here's a follow up - I have a question out to Eagle Aspen tech support but they haven't answered yet. Based on this spec.

http://www.eagleaspen.com/admin/product/fujian/file_230.pdf

the Super Home Node introduces 7dB loss per output for the modulated signal. There is also listed a 2dB amplification gain for antenna input but it is unclear whether that is a +2 gain for each output or just for the original signal. Does anybody know what the antenna gain/loss per output of the Super Home Node is?

The way I read it is that there is a 2 dB gain in the antenna input. Does that translate to +2 dB gain on each output? I don't know. I'd say try it first and see how it goes. If it doesn't work you may just need an amp.

If you look at the PDF file, slide 14 they say: "Antenna to RX +3 dB gain". So it looks like the 2+ or 3+ gain goes to all outputs.

That sounds reasonable. I wonder why the Eagle Aspen specs do not allude to this? Now I understand where the mistake on page 6 comes from. They have the Super Home Node gain listed as +3. But actually it should be a -7 for the example they are conveying. The end calculation of -0.5db for channel 69 correctly assumes the -7db loss instead of a +3.

Thanks again for all the help.
