Basedon Cebik W4RNL (sk) design that is reproducible. Build a truly portable 3-element Yagi-Uda antenna that does not require a matching element. To be prec BuildingUHF Antennas. Published in QST magazine (August 2006). This method of construction can be used on most UHF through "low" microwave Yagis, and is especially useful for the 33, 23 and 13 cm bands; These antennas were made with this process, and tested on this back-yard antenna range. I like to use the basic DL6WU wideband Yagi designs 2However, antennas < /4 in length appear highly capacitive and become inefficient radiators. For example, the impedance of a /4 antenna is 36.6 + j0 . the impedance of a /8 antenna is 8 - j500 . To remedy this, several techniques are used to make an antenna "appear" to be /4 .

Cell phone signal boosters improve voice, text, and data signals for 10X better cell YagiCell Antenna TP514 is a roof antenna and in most cases cannot be attached directly to the device (wifi router, signal booster, etc.) without some type of cable converter/adapter. This is the directional antenna and you will need to know the direction of your source signal. This antenna is for a cell phone booster with 50 ohm cables Vay Nhanh Fast Money.
