An indoor antenna is supplied with the radio. I have used it on the top floor of my house with no issues. If you need an outdoor antenna, you may want to select an after market antenna. We have not gone looking for a specific antenna to recommend. If there is sufficient interest we can go look for and qualify one, but most any should work fine.
