External Antenna port daily driver on Verizon

[Billthompson]

After a bit more time and research, I have ordered some parts to work on actualizing this.  I plan to hijack the coax running to the sub-assembly board, along with something for switching.  I'll be using an MMCX jack for my purposes, and will modify the chassis as necessary to accommodate the connector.  I'll post pictures and details once everything arrives.  All of the parts were easy to source from Mouser.com, though one could also get it on Amazon, albeit with a little bit more hackery.

I cant wait to see how it goes.  The patch lead to switch connection is a weak spot.  Would love to see it as easy as aux port.

  My family has been using older phones with external antennas for years to get service in rural areas. 

            What im seeing is most motherboards have micro switches already installed between radio and antenna for factory testing, however they are tough to access and not physically up to repeated cycles.  The micro switches on this s10 board have been removed, new larger solder pads installed and more robust older model switches installed.  First solder attempt was no good but should get second attempt back next week for testing.  Would be nice to have option manufactured into phone.

switches are off a s4 board
