Compared to the WRT Series dipole antenna, the WRT-MON Series monopole antenna takes up much less space inside the product. The antenna requires a proximity ground plane. It installs through a small hole on the product and is anchored by a threaded metal base connected to the coax cable shield.
The WRT-MON Series antenna is available in 2.4GHz. It’s attached to an 8.5in long coax cable with an RP-SMA, SMA or U.FL/MHF-compatible connector on the other end. The RP-SMA and SMA connectors use an RG-174 coax. The U.FL/MHF connector uses a 1.32mm micro-coax.
