External Antenna
Many low-cost yet high-performance external antennas are available at LoRa frequencies.
For 915MHz the following is recommended for beginners:
- TX915-JKC-20 has 5 antennas

Note
- these are dipoles, so performance tend to be better than monopoles.
1. IPX to SMA cable
Connectors
- SMA can be MALE or FEMALE
- IPX has many other names IPEX-1 or U.FL
There are normally 3 cable sizes:
- 0.81mm
- 1.13mm
- 1.78mm (also called RG178 )
Please get thicker cable e.g. RG178 if possible.

Make sure to get the correct MALE or FEMALE version of the SMA connector for your external antenna.
2. Tigertail
If you have a monopole antenna, sometimes you can increase its range with a "tigertail" hack to make it into a dipole.
