The RX-V685 has two (2) transmitting/receiving antennas located on the back of the unit in the upper left & right corners. The antennas are identical, but transmit different frequencies, 2.4GHz and 5GHz. I know these antenna both receive and transmit because I have my RX-V685 "paired" with a tablet device, and a 21 year old Yamaha RX-596 stereo receiver at another location. A Logitech Bluetooth adapter (receiving antenna) is now the Tape-1 input. The RX-V685 allows full house coverage.
Sorry, there was a problem. Please try again later.No. The WiFi and Bluetooth work out of the box, and the set up process was very easy. The unit comes with an AM and FM antenna, so there was nothing else I needed to buy.
