  • amplifier & telular fixed cellular terminal

    hi ...we have some property in mexico about 70 miles south of douglas, az. and i noticed that you sell telular products specificly model sx7t ....now what i am wondering is if there is a cheaper product available as telcel here in mexico sells another product called avvio gd-850t/tf that seems to do the same thing ...also our area has sporadic cell signals or rather good signals but in sporadic areas but if i use a yagi antenna i can get a full bar signal so we are wondering what it would cost to say set up a repeater at the top of a hill, re-beam the signal to our area to cover it more completely

    Yes there are lower cost versions of the fixed cellular terminals but it pretty much depends on what the minimum feature set you need is. Here is a comparison chart for Telular products: http://www.rfwel.com/data/fixed-cellular-terminals.php. For example if you dont need a cellular router capability (web browsing etc) and can do without battery backup then the SX5t or SX5e would be good enough.

    Would this be powered by a U.S carrier or Mexican?

    It is not really practical to implement a repeater far from the terminal but an amplifier connected directly to the terminal works very well in most cases. So something like this: http://www.rfwel.com/support/tech-dr...tgs3_rev1a.pdf (this is based on the Option Globesurfer III which is both a cellular router and a fixed cellular terminal) but the idea is the same for any other wireless terminal such as telular -- all we would need is to change the antenna port pigtail.

    The choice of antenna/amplifier depends on what carrier and hence what frequency band the carrier operates on but the basic setup is as shown.

    One example of a dualband amplifier is: http://www.rfwel.com/shop/?target=pr...product_id=326
    Cables to connect yagi antenna to amplifier: http://www.rfwel.com/shop/home.php?cat=183

    Here are some connection drawings showing example of how you would hook up amplifier/antenna to cellular terminals and data modems: http://www.rfwel.com/kc/application-drawings.php

    Let us know if this is what you have in mind or you have additional questions/clarifications.
