    I got a slimline lnb with swm. Im going to get an antenna so i can pickup the local HD channels. How do I go about doing this so i can send the directv signal and OTA signal over one coax cable per box. I got 3 boxes in my house.

    Diplex the OTA in with a Diplexer and then Diplex it back out at each Receiver that you want OTA.

    Make sure you buy the correct diplexers, but you still may have mixed results.

    SWM and OTA will not be compatible in the VERY near future, i.e. DirecTv is going to use that frequency band, so your only option is to run a new cable to each set for OTA.

    I been thinking about going SWM for awhile but just cant make my self pull the trigger. I have a 5 SWM LNB and a SWM 8 sitting here that I am not gonna use. I also have WB68 that I will use if and when I decide to add anymore DVR's.

    That question would take hours to answer.

    The simplest answer is: One you can return for a full refund if it doesnt work.

    Best place to check would be on avsforum.com in the local HD forum, thread for your area. Distance from the transmitter, electrical wiring in walls, proximity to an outside wall/window all will make significant differences in your choice.

    In general, however, if all your HD channels are on UHF, a "silver sensor" type would be best. If some of them are on VHF, its a crap shoot. I have found, overall, when setting up portable emergency OTA, the best bet is to use an outdoor antenna, like a Channel Master 4221, which is a 4 bay, and tucking it away in a closet with coax running to the tv, if practical, or attic mounting, if possible.

    I've had good luck with the Channel Master 4220 (small 2-bay UHF). For diplexing I am using a Channel Master 4002 (outdoor) and a 4001 (indoor) diplexer sharing an SD DTV signal. The antenna is mounted on sat dish tripod leg (Rohn TRT60 5ft. HD Tripod) on north facing side of roof, elevation ~40 ft. Fortunately in my location, broadcast antennas are due north, and the sats are south, so the Dish and antenna don't get in each other's way. I am at maximum signal strength on all stations, including hi VHF ones, but I am only 10-11 miles from the towers here.

    I will be setting up a SWM-8 shortly, I am going to be using two legacy ports on the SWM-8 to feed an existing SD TiVo DVR, I will be adding a SWM compatible DVR next year. My plan is to keep the diplexers in place, outdoor between the unpowered legacy port of the SWM-8 and anntenna, and indoor diplexer on the unpowered coax (obviously). I guess the SWM-8 can now handle OTA signals without external diplexers, but I've seen mixed results reported, so I think I am going to use my existing diplexers.

    Best advice can be found in the "Local HDTV Reception Forum" at http://www.avsforum.com. Find the thread for your nearest city. There you can ask folks familiar with your area what antennas work well.
