That was why the ancestors told you not to put a 15 meter dipole on the same coax with them. $99.99. Netherlands. 0dB would be considered you just as you with nothing artificial. Therefore dB is not an absolute measurement but rather a ratio. You should also note that you can be breaking the law with too high a gain of antenna -- the FCC limits unlicensed transmission in the 2.4 GHz band to 1 watt EIRP (equivalent isotropic radiated power). . Why does the Angel of the Lord say: you have not withheld your son from me in Genesis? Some people here on the subreddit have shown ranges of around 70km next to a sea or ocean. This would be like a 7dB antenna. For more information, please see our Does higher dBi mean further range, for an antenna? How can I make my wifi faster? Vertical. It only means that transmitters have to work harder to establish communications with receivers and vice versa. This antenna range calculator calculates range of an antenna based on antenna transmit power, Enter the Total link distance (in Miles or Kilometers), if you do not enter an Obstacle distance (in Miles or Kilometers) the calculator will use the mid-point for all calculations (Note: assumes antennas at same height). As shown in the table below, the latest wireless 802.11 standard has the best coverage in term of distance.
