## Customer Reviews

### ⭐ No go
*by T***E on September 2, 2015*

Did nothing. In fact, it made the signal less readable. Bummer.

### ⭐⭐ Is the ramsey SA7 any good.
*by L***N on August 30, 2009*

Well to answer the question as to whether the SA7 is any good you have to ask yourself what you want from a preamp? The SA7 is ONLY capable of compensating for loss of signal between your antenna and receiver. Only if you put the SA7 in a long feed line at the antenna will you see any improvement. Plugging this in at the receiver will do nothing or worse, attenuate(weaken) the signal. It will not turn your antenna into an active antenna. If you want an increase of signal and more selectivity pay a lot of money for a bigger, better, higher and maybe even directional antenna and more expensive feed line(coax).I have also had one of these on my Oscilloscope and signal generator. It gave about 0.05µVolt increase at 20Mhz which does not constitute a +20db increase, more like +4-6db. It is also hampered by nulls about 10, spread out more or less evenly up and down the frequency coverage.So in conclusion, If your want more, better defined and stronger signals. Don't buy a Ramsey SA7. Buy a better antenna and feed line.

### ⭐⭐⭐⭐ Does a good job.
*by V***I on March 7, 2013*

Purdhased this amplifier as a preamp to my frequency counter. This kit allows my counter to display frequencies that are of the low level. The reason I gave it a 4 star is that the kit requires you to solder a surface mount resistor. It can be a challange if you have never worked with surface mount components.
