 Performs as advertised, but beware of noise Sep 29, 2005
By Major Pagefault
I purchased the Channel Plus DA-520A 20dB signal booster in order to boost my cable signal due to significant (-19dBmV @ 700MHz) attenuation caused by a 6-way splitter at the ingress junction point of my house.
I found that this booster performs exactly as advertised. It brought my signal up to right around 0dBmV - the perfect level. However, I found that it also appeared to introduce a significant amount of noise; some RF-sensitive equipment I had in the vicinity of the device started showing signs of interference. I also found that my SNR dropped by 4dB (from 34dB to 30dB) when comparing the signal against a competing 15dB device. I am not certain whether this may have been due to my overdriving the line at the lower frequencies, but if so, an adjustable gain control would have been a handy and eminently useful addition.
So, in a nutshell, this device does exactly what it's supposed to: it boosts the input signal (and perhaps the input noise too). However, I found the device to emit more RF noise than a comparable 15dB booster, both on the wire and off it.

This product is very easy to setup and boosts the Cable signal. With HD signals, you need a strong signal. This product is a good value for those who want strong signals on all TVs.

Cable Amplifier Jun 09, 2008
By S. Lipoff
This is a bidirectional amp that will work with a cable modem or two-way set-top box
however it lacks a variable forward gain adjustment. It can be overloaded if the input
signal is too high but is useful if you install it after several splits so the
input signal is weak. It has an external power supply which connects to a
dedicated f connector on the unit. It would have been more useful if you
could power it with a power inserter on the same output coax that has the
output RF signal.
