Follow up: instead of microwave antennas and wave guides in order to have a communication between two radios, we are going to use a coaxial cable as a direct connection of the two radios. the three items i was looking for serves primarily as a attenuator. Because it might cause the reciever to be burned due to over power form the transmitter...
any people out there knows where to buy this items locally pls let me know... Thanks!
