AR300m vs AR300m-ext

If I don’t attach the antennas to the AR300m-ext, do I still get the wireless coverage comparable to the AR300m?

You have to attach antenna to AR300M-Ext, otherwise you will not get signal from 5 meters away.

@alzhao Won’t the transmitter get damaged without the antenna connected? Usually if you don’t have an antenna connected all the power that would be transmitted goes nowhere and blows the transmitter.

If you connect or disconnect the antenna while the router is powered on, it mag damage the radio.

But use without antenna, I never heard that it can damage the radio.
