those are all preeminently mounted on the top of the RV and cost a couple of thousand to purchase and get installed and in a lot of locations they will not work because you cannot park with clear shot to the sats. I have always used a tripod and until the Hybrid LNBF had no problem locking on. It really is not the Hopper 3 that is the problem it is the Hybrid LMBF setup. On the non Hybrid LNBF you could tell which LNB was for which sat and if one had problems locking on you could cover the others and peek that sat usually with skew. With the Hybrid the LNBFs are not defined physically but by the system the first sat to lock get that LNBF, as I understand it.
Yes there is a multi-switch inside the LNBF head. Any coax can be electronically attached to any LNBF. Early on I found that the default for a DPP 1000.2 was 110 LNBF to the coax cable. That is why I used a meter that let me generate a 22 KHz tone on the coax to electronically select the 119 LNBF.
The early DPP 500 LNBF multi-switches could be toggled with voltage,12 v or 18 v I think. The tone was an evolution. When satellite 129 was added then dseq commands were used to select the LNBF.
The foil may or may not work because if the default electronic connection is to a covered LNBF, you get no signal. You can force LNBF selection by setting the tuner in the receiver to the satellite you want. With multiple tuners, that can be a turkey shoot.
I believe that the DPH Hybrid multi-switch works similar to the DPP multi-switch except is probably doesn't care about voltage selection any more.
Smart meters like the First Strike and the Super Buddy generate dseq commands for LNBF selection. I have had to setup the tripod a couple of hundred feet out and using the receiver just was too difficult. Smart meters allows me to setup at the dish and run the cable after I know I am locked in.
My Trav'ler cost $1200 and a couple of hundred to install so I don't know how you can spend a couple of thousand to get one installed. A typical year for us is is 50+ stops and if we need the tripod, maybe 4 times in the west. This year we are in the east and want HD Locals so in out 58 stops, 35 needed the tripod so we could use a EA DPH head. I had several years with out the Trav'ler and it was a boon to setup. A more perfect world would be a Trav'ler that can do the WA and the EA but that is physically impossible because of the LNBF spacing. So the Trav'ler for most of the time and tripod when in the East.
And I really like the Hipper 3. No way I would go back.
