I bought a condominium in another city from the one in which I live. I'll be there only about 4 weeks per year. At home, I have a slimline 5 dish, an HR-20, and an HR21. The condominium has RG-59 cabling inside and is serviced by an old round dish for standard def. From the dish to the service entry of the condo, there is RG-6. I want to update the dish for HD reception. The installer says it will be difficult to pull new RG-6 because it is a flat without an attic or crawl space. He says the RG-59 can be used and wants to install a slimline swm dish. Questions: Is the installer correct concerning the RG-59? Assuming he is correct and it will work, will one of my current receivers work at both locations (so I can take it with me to the condo and bring it back home)? If not, which receiver should I buy in order to be able to use it both locations?
