If you live in a rural area with limited cable Internet coverage, you may own a wireless broadband device that operates on the new 700-MHz band. Radio properties of the 700-MHz band enable wireless companies to broadcast Internet and voice data over long distances, without losing signal strength from environmental interference, such as trees and buildings. A high-gain antenna built for the 700-MHz spectrum can boost the signal to your broadband device.

Things you need
- Coaxial cable with connectors, 75-ohm, 1 foot long
- Pigtail cable, low-loss, with female F-connector and broadband connector
- Wire-stripping tool
- Utility knife
- Electrical tape
- Ring terminal lug, 18-gauge
- Small piece of twine
Cut a connector from one end of the coaxial cable. Remove four inches of insulation from this end. Roll the braided sheath back over the cable housing, exposing four inches of insulated inner copper wire. Remove the plastic insulation from the inner copper wire. The four-inch braided sheath should be pulled down over the cable, in the opposite direction of the copper wire. Secure the sheath to the cable housing with electrical tape.
Measure the length of the ring portion of the terminal lug. Trim this amount from the tip of the coaxial copper wire. Crimp the ring terminal to the copper wire. Make sure the distance from the base of the copper wire to the tip of the ring terminal is four inches. Tie a loop of twine through the ring.
Hang the antenna from the twine. Connect the F-connector end of the pigtail cable to the free end of the antenna. Connect the other end to your 700MHz broadband device.
Tips and warnings
- Make sure the coaxial copper wire -- including the ring terminal -- and the braided sheath are both four inches long.
