I came across this special amplifier, guaranteed to boost and smooth your signal.  I can't wait to order one.



I hope the photo comes through.

Sam...

 

 Cool!  Wonder how many were sold, and how many people to this day think it did something? <G>

 

 If I had "invented" it, I would have put in some more useless wires and parts to make it look like the trim pots connected to something. Just in case someone opened it up, as was done here! And maybe run the coax through another, sealed, interior box so that it's routing wouldn't be so obvious. 

 

 At least the power light is real!

				Can you get a special deal If you order

several of these, like 10% premium for 10 or more?

				I am sure many on the list are as anxious to

have one of these beauties as you are.

Sam,

 

 The frequency range shown on the cover implies that you are going to use it for VOR amplification, since COM is a two way street, and any amplifier in a simple in-line connection will interfere with one way.

 

 I see several things wrong with the amplifier and its use.  First, it is poorly built and may not stand up to aircraft quality standard.  Second, an in-line amplifier can boost a signal, but it cannot "smooth" unless it filters our certain frequencies.  If you know the "smoothing" function, then you can determine what frequencies are being attenuated.  Are these frequencies crucial to your application?  Third, any in-line active amplifier will add noise.  Do you know what its SNR is?  If it is low enough, it may be tolerable.  If it isn't, you're just adding another problem.

 

 Most equipment, especially our aviation equipment, is made to connect to antennas without amplification to avoid the above problems.  Do you have a specific problem with the system you're trying to fix?  Can it be fixed without amplification?

Simon,



The frequency range on the box actually specs broadcast and bands of cable TV, airband anything
