Log Periodic Yagi Antenna
This antenna's directional property
"compresses" the signal into a powerful beam that is 4 times
more powerful in the desired direction. They are the ideal antennas for
scanners, wireless LAN's, and other wireless devices. When you need a
dedicated point-to-point link, they have no equal! Their maintenance
free construction on rugged FR-4 material boasts the added advantages of
no tuning and no fragile antenna elements to break or twist! The small
size and wide bandwidth makes them ideal for feeding reflector antennas
such as easily constructed corner reflectors or parabolic grids. Pick
the one that's right for you and start enjoying the fruits of a well
designed system! This product has a shipping weight of 0.30 pounds. |

| Log Periodic Yagi Antenna This small log periodic yagi (We call it the LOGI!) is ideal for getting the maximum performance out of any UHF to low frequency microwave wireless system. The directional property "compresses" the signal into a powerful beam that is 4 times more powerful in the desired direction. It is the ideal antenna for scanners, wireless LAN's, (Compare the price of this antenna to what your WAP manufacturer charges for an similar antenna!) and other wireless devices. Its directional properties make it exceptional well suited for point to point links. Constructed on rugged FR-4 material, it requires no tuning and has no fragile antenna elements to break or twist! Covers the entire 900 to over 2,500 MHz frequency range! Its small size and wide bandwidth also make it ideal for feeding reflector antennas, such as the easily constructed corner reflector grid which we discuss in the manual. This antenna has an gain of 6dB across its entire range. After we got the right connectors, we hooked up one of these babies to a wireless access point we use here, it's just a standard consumer 802.11b device. When we replaced one of the little whip antennas with the Logi, directionally we got more than 2x the distance using a standard internal antenna PC Card. That's pretty good! When we tried the Logi with a simple, inexpensive reflector using the same gear... We ran out of room to test it! At 1/2 mile away, using a standard PC Card, nothing special, we still had 100% signal! So, if you need to make a link across the street, or into the next town... this antenna may be for you! This antenna comes with a short length of RG58 and a BNC connector. If you plan to use this antenna for 2.4Ghz operation (Like for a wireless LAN) you should replace the cable with LMR195, which is what we used during our WLAN testing, for best performance. This product has a shipping weight of 0.50 pounds. |
