Well I was able to do some smart internet online shopping and stretch my "Blood Money" Stash Account and ordered a Winegard Trav'Ler SWM3 (SlimLine SWM) automatic open array antenna for the motorhome. My Safari MH has RG6 Coax that originates in the front entertainment cabinet, somewhere splits via a splitter with one path going to a basement coax cable outlet, and the second path going to the rear bedroom TV cabinet. I would like to replace both coax cable runs with HDMI cable runs. I have two 40 foot runs of HDMI & a HDMI Splitter, and have tested the setup laying the HDMI cables loosely in the hallway. Works great. Now the hard part, FINDING the pathways of the old RG6 cables/runs through cabinets and wherever the Coax runs, and re-running the new HDMI cables. I have heard that you can buy a tool called a Tone generator. You hook up the beginning of the RG6 coax to it and then with the "Probe Half", you poke around and if you are close to the cable run it emits a tone, ergo the cable pathway. Got any good tips/techiques/tools, etc.???? Or should I just bite the budget bullet and go have it done at Camping World in Wilsonville Oregon? If anybody familar with these tone generators, what make/model do you recommend??? Any techniques should I pay attention to???
