09 Jul 2002 12:35 UHF/VHF wireless modules??

Does anyone know where can I find a wireless module (400-450MHZ) with 1-4W of output power. All I have found is with low power.

Thanks a lot,

You can add a 1 W power amplifier to the transmit section of your low power wireless module:

But watch out for strong transmitter signal leakage into the receiver. Depending on your design/application, this might be a problem.

It is for using them with license, so no problem.

You can find them Nowhere untill you plan to make one for your self or if ready to submit the paper work for the licenced band you own .Illegally you have got plenty of ways to make them why only 4W
you can make 20W after adding plenty of POWER almplification stages and Big heat sinks ,,,,, Hope you will not do the same with the POLICE or MILITARY allocated wireless space and if you do you wont come to elektroda any more Wink
