Picture of Adding an External Antenna to a Clear Motorola CPEi25150
Clearwire does not currently offer any modems that have an external antenna port. Coupled with an outdoor directional WiMax antenna, you can greatly improve your connection quality and speed with this modification.


Parts list:
Murata Probe - MXHS83QE3000
- Hot glue
- Outdoor rated SMA cable
- WiMax outdoor antenna

Step 1: Take the modem apart.

Use a dull flat object to pry the base of the modem off. I used a butter knife and carefully popped loose the tabs holding it together. Be careful not to destroy your modem's case in the process. After the bottom is off, the board should slide right out.

Looking to add an external antenna to my new Clear Ispot.
It has 2 of the same connector / test point connectors on the board.
Did you find a pigtail with the MXHS83QE3000 probe to sma or make it up.
Where did you find the MXHS83QE3000 probe.
Thanks.

Did this have any affect on latency? If so how?

Yes, you can see an improvement in ping speeds. Not anything substantial though. What you are probably going to notice more is the increase in connection quality by removing external interference.

This is intriguing. Our CLEAR reception deteriorated in recent weeks. This might be an option I want to consider. But, we have also had a modem need replacement. CLEAR would probably hesitate to replace a modem I had open and drilled, should we run into that problem again. Maybe I could just use the modem outside of its case without drilling.
