Aerials and antennas

-Build your own portable, mobile and fixed antenna designs-- ARRL's VHF/UHF Antenna Classics includes antenna project articles gathered from the 1983 to 2003 issues of QST. Designs include ground planes, J-poles, mobile antennas, Yagis and more. Authors include well-known antenna designers such as L.B. Cebik, W4RNL, Dick Stroud, W9SR and Steve Powlishen, K1FO. VHF and UHF antennas are among the smallest and often easiest antennas to build. Many of the projects included in this book require inexpensive parts which you can find at most hardware stores. Build a better antenna for your hand-held radio. Construct a 2-meter Yagi that will rival similar commercial antennas. Build a dual-band vertical for 146 and 445-MHz. The results will be rewarding!

5.8 GHz Dual Patch antenna by WA5VJB - this listing is for individual antennas WITH connector attached. This compact 5800 MHz quad patch antenna provides high gain across the narrow frequencies very commonly used in wireless systems. This is a wifi antenna that can run data links, dish feeds, wireless systems, ATVs, repeaters and beacons. It has 8-9 dBi gain. This 5.8 GHz antenna performs well for drone FPV applications. Each antenna weighs less than an ounce. They are 1" tall, 2.25" across and a fraction of an inch thick. I also sell 5.8 GHz quad patch antennas by WA5VJB without any connecting cables. See my other listings. Free shipping for U.S. customers.

The MFJ-993B IntelliTuner lets you tune any antenna automatically balanced or unbalanced -- ultra fast. It's a comprehensive automatic antenna tuning center complete with SWR/Wattmeter, antenna switch for two antennas and 4:1 current balun for balanced lines. MFJ's exclusive IntelliTuner, Adaptive Search and InstantRecall algorithms give you ultra fast automatic tuning with over 20,000 VirtualAntenna Memories. You get a highly efficient L-network, 6-1600 ohm matching at 300 Watts SSB/CW or extra-wide 6-3200 Ohm matching at 150Watts SSB/CW, 1.8-30 MHz coverage, Cross-Needle and digital meters, audio SWR meter, backlit LCD, remote control port, radio interface, heavy-duty 16 amp/1000V relays. It learns while you're having fun As you're ragchewing, contesting or DXing, your MFJ-993B is learning! When you transmit, the MFJ-993B automatically tunes for minimum SWR and remembers your frequency and tuner settings. The next time you operate on that frequency and antenna, these tuner settings are instantly restored and you're ready to operate in milliseconds! MFJ new VirtualAntenna Memory system gives you 4 antenna memory banks for each of 2 antenna connectors. Select up to 4 antennas on each antenna connector. Each antenna has 2500 memories, 20,000 total. Intelligent ultra fast tuning MFJ's InstantRecallTM first checks its memory to see if you have operated this frequency before. If so, tuning is instantaneous and you're ready to operate. If not, MFJ's IntelliTuner algorithm - - based on MFJ's famous SWR Analyzer technology - - kicks in. It measures the complex impedance of your antenna. Next, it calculates the components it needs and instantly snaps them in. Then, it fine tunes to minimize SWR -- you're ready to operate. It's all done in a fraction of a second. When the impedance is within its measurement range, the MFJ-993B is the fastest automatic antenna tuner in the world. If it can't accurately determine impedance, MFJ's AdaptiveSearch algorithm goes into action. Frequency is measured and relevant components values are determined. Only those values are searched for ultra-fast tuning. For even faster searches, you can set the target SWR to 2 (settable 1.0-2.0). You can manually tune when you can't transmit (for listening out of ham bands). Cross Needle and Digital SWR/Watt Meters Lighted Cross-Needle and digital meters lets you accurately read SWR, forward and reflected power at a glance. An audio SWR meter lets you hear the tuned SWR when you can't see/read meters. Turn on a highly visible, instant response SWR LCD bargraph when you need it. Backlit LCD Display An easy-to-read backlit LCD displays SWR, forward/reflected power, frequency, antenna 1 or 2, L/C tuner values, on/off indicators and other information. The MFJ-993B is a compact 10W x 2¾H x 9D inches.  Requires 12 volts for lamp -   included Remote Control Plug in the MFJ-993RC, remote control and use your tuner elsewhere remotely. MFJ-993B Interface Pre-wired Cables  Allows automatic tuning of your MFJ-991B/993B/994B IntelliTuner through radio.
