Ok Tnx
Oh sorry...........didn't see the question. It's the ARCXT basic. Use it for the 396XT and 996XT and I understand it will work with the P2 series with upgrade.

To answer your question, as a second career for 34 years I did commercial and private satellite tv installations and maintenance. My equipment distributors also sold cable tv amplifiers as they were customers and had their own satellite tv antennas receiving configurations. Oversimplified explanation, they ported the satellite tv base band signals to their facility and converted each baseband A/V signal to the appropriate tv channel that usually was the same as if you received whatever tv channel off air for your tv. Then however many channel the cable system were were inputted to a signals combiner and transmitted through the cable tv coax distribution lines configurations throughout the city, county, etc.,with individual taps made by the installer and coax run to the appropriate home or business.
So now the satellite tv A/V baseband satellite tv signal has been converted to vhf ch. 3 tv just the same as if you had received it off air on your tv antenna..
The cable company could have assigned whatever programing service using a single tv channel amp on any one of 57 different tv channels at the facility but they try to match up their cable tv channels where appropriate to the FCC tv channel authorized for use...and so forth for all the tv channels available for customer viewing. For programing like movie services, sports, etc.they can use up to 200+ individual cable tv configured channels. For example, HBO could be on ch. 185 or whatever.
Often there is a requirement to amplify the signal strength of the delivered cable tv signals usually involving a multi tvs viewing situation requiring signal splitting for noise free plus reception. They are available for low/high vhf and uhf. I bought both models for use in receiving radio signals within those amplified frequency ranges instead of using it for off air tv reception enhancement.
They are not cheap because they are commercial grade and used in environments who accept high prices used in their environments can require a special power supply purchased separately. Also, you had better know what you are doing. Otherwise, these items can be damaged like any other electronics. One down side for the uhf models available today is the FCC restricted the top uhf tv channel not higher than ch. 57. The 804-870 mhz. range we are interested no longer is supported. The range coverage drops off significantly after tv ch. 57 for obvious reasons. Only the older uhf models supports the full 800 mhz. range.
For large cable tv systems which those large channels available a special amp probably is made for those systems.
.
As for their cost, major manufacturer's such as Blonder Tongue are expensive and much more than you would want to pay. Do some Google searches to get an idea of how bad. They probably will not sell factory direct to the public only through an authorized distributor.
