Use an external antenna when you can't mount the EnGenius base up high enough for adequate range. It has two clamps to attach to a piece of pipe or antenna mast, but can also be attached to a wall, post, tree or chimney with proper hardware. It's excellent for ranches, farms, resorts, camps, warehouses, industrial parks, auto dealers, mines, parks, oil fields, campuses, etc.
TWO CABLE CHOICES: PLAN CAREFULLY
Shorter cable means more power for longer distance conversations.
The antenna can be mounted upside down, if necessary, and hung from the ceiling in a warehouse, factory, or even an airplane hanger.
- Plan your installation carefully. If you can use the shorter (10-meter) cable, you will deliver a stronger signal to the antenna, and save money.
- In April 2007, EnGenius introduced a new higher performance antenna design, supplied with a new lower-loss LMR400 coaxial cable.
DB gained (or recovered from loss) using new LMR400 vs. older RG213 coaxial cable:
10-meter cable = + 1.23 DB
20-meter cable = + 2.46 DB
Additionally the old antenna had 4.5Dbi gain, while the new antenna has 6.0Dbi. This total gain for each new antenna with cable as
compared to the old antennas is:
10-meter = +2.73Db
20-meter = +3.96Db
- EnGenius uses special reverse-thread cable connectors that are not generally available, so it will be difficult to cut a cable and install a new connector. Changing the cable length will void
the FCC certification for the phone it is used with.
- If you leave excess cable coiled up, you will sacrifice performance. Stretch it out or make loops at least six feet in diameter
An antenna splitter will lets you use one antenna outdoors plus one indoors, or antennas on both sides of a firewall, to increase coverage.
You can also use two antennas outdoors for a figure-8 coverage pattern.
The splitter is packaged with a 1-meter coaxial cable with EnGenius connectors.
Don't forget to install the lightning protection kit. It can save your expensive phone. We recommend surge protection for AC power and phone lines, too.
