RF Control

I want to control my arduino due with RF.. the transmitter is usual but the receiver is having 8 pins as i mention below

RoHS 434Mhz
GND DATA DATA VCC VCC GND GND ANT

How should i use it??

Sounds like you have one of the good receivers!

The connections are the same - they just provide you with extra Vcc and Gnd pins on the side. Connect the antenna to the ANT pin, instead of the little unmarked hole in the board like the cheap receivers.

what should i use as an antenna??

A Wire May Be...!

A wire - same length as you would use on any 433 mhz RF module. The normal cheapo ones need an antenna too.
