SparkFun GNSS Chip Antenna Evaluation Board
US$38.28
The SparkFun GNSS Chip Antenna Evaluation Board makes it easy to test out various sized GPS antennas and geometries. Six different chip antennas have been populated on this board, each with a U.FL connector to attach your chip to the antenna! We've even v-scored the board so you can snap the six antenna's apart and just have the one you need. If you aren't picky about your antenna and/or each of the antennas work well for your applications, you will get six antennas to use in various project. Since these are GNSS antennas, they will work with GPS as well as GLONASS, Galileo, BeiDou, and other worldwide systems.

ANT-9145 SMA to uFL/u.FL/IPX/IPEX RF Adapter Cable
US$3.49
This RF adapter cable adapts the u.FL connection on an electronics module to an external antenna SMA connection. Often times, small electronics save space by using a u.FL connector (also called uFL, IPEX, IPAX, IPX, MHF, and AM) on the PCB. This panel-mount SMA cable will connect to an antenna with RP-SMA (with pin in center). Most WiFi devices/routers that have a connector use RP-SMA.

Adafruit RFM96W LoRa Radio Transceiver Breakout - 433 MHz - RadioFruit
US$30.73
Sending data over long distances is like magic, and now you can be a magician with this range of powerful and easy-to-use radio modules. Sure, sometimes you want to talk to a computer (a good time to use WiFi) or perhaps communicate with a Phone (choose Bluetooth Low Energy!) but what if you want to send data very far? Most WiFi, Bluetooth, Zigbee and other wireless chipsets use 2.4GHz, which is great for high speed transfers. If you aren't so concerned about streaming a video, you can use a lower license-free frequency such as 433 or 900 MHz. You can't send data as fast but you can send data a lot farther.'
