Cell Phone Booster and Wifi Amp Antennas on Same Mast?

Hello, friends!

Based on a lot of reading here and elsewhere, I have decided to invest in a cell phone signal booster and a Wifi amplifier. We won't need these often, but we do stay in several places where they would come in handy. Since I won't use them all the time I've decided against a permanent antenna installation, but would rather mount both antennas on the same, temporary mast that I could set up as needed. If I use a cell booster antenna such as the omni-directional Wilson trucker-type or something similar on the top of the pole, then use a flat panel directional antenna below that for the Wifi, I figured I could set up the mast, point the directional Wifi antenna in the direction of the campground Wifi, and be all set.

Do any of you folks who understand the magic of electronics know of any idea why this would not work? If it matters, the cell booster is the Cyfre CA-819, and the Wifi booster is the Alfa AWUS036NHA.

Thanks very much!

  • I use a Wilson Sleek for Verizon. I stick my JetPack in the cradle and use a 12" magnetic mount antenna outside my 5ver. That works for my cell booster and wifi.

    On my WILSON SLEEK Cradle setup I also had to separate the external antenna mount to not interfere with my DROID Cellphone Antenna sitting in the cradle. They had be on a different vertical plane more so than mounted side by side. Interference would show up as decresed signal strength bars on the Droid unit. My setup had two WILSON SLEEK Cradle setups one in the truck and the other in a nice outof the way area inside the RV trailer. You can think of the WILSON SLEEK Cradle as my DROID or MIFI UNIT docking station.

    In my case it was more noticeable being used in my truck cradle setup as both indoor and outdoor antenna were usually in the same vertical plan. In my RV setup my external antenna is mounted on the side of the roof so that gave a lot of vertical separation when my DROID was sitting in the Wilson Cradle.

  • I seem to recall you want to separate antennas by a minimum amount calculated by the wavelength of the band they operate in. 2.4g ISM I think is around 13 centimeters? Cell-phone is kinda all over the place 700mhz to what, 1900mhz? Going for the longest wave, that's roughly 43 centimeters or a little under a foot and a half?

    If you have room on the mast to separate them by 43CM, go for it.

    There's HAM folk on here that can either confirm this or let you know I'm full of **** :)
