13. Question:
We have a customer who previously had the NV-600W (regular antenna) and we sent them a
NV-600W with the 5db antenna (high power output) to replace the original unit when it failed, but the
new unit with 5db antenna has less coverage than the original unit. Can you please send me the
NV-600W wireless configuration settings to optimize the range of the high output antenna? If they are
the same, why is the NV-600W with the 5db antenna, providing less coverage? Please advise.
Answer:
Please note that the two antennas have almost the same coverage range, the difference between the
two antennas is the Gain pattern shape (the 5dBi Gain pattern shape is butterfly and the 2dBi Gain
pattern shape is chubbier), and also the 5dBi antenna has higher penetrating power (ex. Through
walls).
So regarding this issue, we don’t think that the 5dBi is providing less coverage, we think is because of
the Gain pattern shape. Furthermore, the actual performance will vary depending on the environment
factors.
