RF Antenna for PCB

I need to connect an antenna to my RF receiver which is built on PCB. Where can i find an SMT of through-hole antenna connector to solder it on PCB and connect an antenna to it.


thanks

Digikey has all kinds of RF connectors.  Here is one of the relevant pages.

I recommend you to use RG-58 connector beside the specific antenna model.

Well, antenna is a big issue, it is hard to determine your specific antenna need with few information, antenna model will depend of:
- Frecuency
- Transmission and reception capabilities
- Gain
- Omni or directional needs
- Environment requirements

I have suggested RG-58 BNC connect because it is one of the most used for **reception** antennas, including 70 cms UHF, and PCB mountable connector is easy and cheap to find.
Maybe you can browse this site: www.antenex.com

What size is the PCB, and what is the range of the receiver?
In many applications an antenna can be fabricated on the pcb.
BNC is rarely used in new designs. Most common types are MMX, SMA, or SMC.

It is not a matter of fashion, every connector has different capabilities, while BNC has a comparative low bandwidth (enough for 70 cms RF), it is has 1000's of  secure insertion/extraction cycles, far many times the expected live of other mentioned connectors, making it still the best option for field communications, that's why most removable antennas for handy talkies are still BNC.
