I am using 433 RF module (tx and rx) through HT12 encorder and decorder. Which is working fine. The only problem is the range. Can any one guide me how to make antena on the pcb or using the wire wrap on 1/4 screw to increase the range
Regards

From memory the antenna should be about 17cm long.
A single straight piece of solid core wire works well,it works nearly as well coiled.
Don't wrap around anything metallic.
