18dB Channel Plus RF amplifier best buy. This RF amplifier product offers a robust power supply and great EMI rejection. It includes grid mounting ears for the Model 2619 Rack-mount Grid. The DA-500A is fully compatible with HDTV Television signals.
Review:
The product is as it is described. It amplifies your signal before splitting it, so that you do not have any signal loss. The one thing someone must understand is that it amplifies signal that already exists, it doesn't create signal that isn't there. So if you place it at a point after it has already been split a few times, it wont do anything for you. I live in an apartment, and I guess our cable signal is not the strongest by the time it reaches our apartment. So unfortunately, I don't get the greatest signal ever.
However, when I attempted to split my signal three ways, the signal leading to my computer tv tuner turned out to be extremely degraded before I got the amplifier. Upon adding the amplifier, that signal now comes in as clear as my television does. The television signals seems to be slightly better as well, however if it is better, it is by such a small amount that i can't really say for sure that it really has improved.
This is a great device if you want to split your cable about three ways, assuming that each split causes roughly a loss of about 6.5 db. Any more splitting then that and you are going to face more signal degradation. This device can not be plugged in with your Internet, or it will cause it not to work. I had to rewire it so that my cable Internet and digital phone split before it hit the amplifier. When it was directly plugged through the amp, I lost my phone and Internet.
Besides that, it is a good device to prevent signal degradation when splitting cables. However, if you are not splitting cables and are simply trying to amplify 1 signal to 1 television, its not going to do anything for you, in fact, the only thing that would is a call to your cable company.

About RF Amplifier
An RF power amplifier is a type of electronic amplifier which is utilised to convert a low-power radio-frequency signal into a larger signal of significant power, usually for driving the antenna of a transmitter. It is usually optimized to have high efficiency, high output Power (P1dB) compression, good gain, good return loss on the input and output, and optimum heat dissipation.
The basic applications of the RF power amplifier include driving to another high power source, driving a transmitting antenna, microwave heating, and exciting resonant cavity structures. Among these applications, driving transmitter antennas is most well known.
