MFJ 929

The MFJ-929 IntelliTuner-CompactTM lets you automatically tune any coax fed or random wire antenna 1.8-30 MHz at full 200 Watts SSB/CW. It can match 6-1600 Ohms (SWR up to 32:1) - - thats a 50% wider matching range at a higher power level than lesser competing products. You get a digital SWR/Wattmeter with backlit LCD, antenna switch for 2 antennas, built-in radio interface and built-in internal BiasTee for remote tuner operation. MFJs exclusive IntelliTuneTM, Adaptive SearchTM and InstantRecallTM algorithms give you ultra-fast automatic tuning with over 20,000 VirtualAntennaTM Memories. MFJ VirtualAntennaTM Memory MFJ new VirtualAntennaTM Memory system gives you 4 antenna memory banks for each of 2 antenna connectors. You can select up to 4 antennas on each antenna connector. Each antenna has 2500 memories. 4 Times the Solutions! MFJ-929 gives you 256 values each of capacitance and inductances for 131,072 matching solutions. Thats 4 times the 32,768 matching solutions of competing products with only 128 L/C values each! Highly intelligent, ultra-fast tuning! Dont be fooled by competing products claiming fast search times -- if you have a quarter of the matching solutions, of course, it takes less time to finish but its not faster. MFJs faster speed comes from advanced technology and software algorithms not from fewer matching solutions. MFJs IntelliTuner-CompactTM actually measures complex impedance -- R and X --of your antenna, computes the L-network values needed and snaps in those components to give you an instant match. If the load is out of measurement range, AdaptiveSearchTM determines the smaller sub-set from all solutions that can match a safe load -- and then searches only that subset -- others search through far more solutions. Digital LCD SWR/Wattmeter An easy-to-read, two-line, 16-character backlit LCD displays SWR, peak or average forward/reflected power, frequency, antenna 1 or 2, L/C tuner values, on/off indicators and other info. They are selected from easy-to-understand menus -- not complex combinations of buttons you can’t remember. A fast-response, high-resolution bargraph gives you an auto-ranging 20/200 Watt power meter. You get 60 segments each for forward and reflected power and 36 segments for SWR -- try that with an 8 segment bargraph that makes you change power ranges and doesn’t even give you reflected power! You can read inductance and capacitance directly in uHy and pF. This turns you into an expert L-network designer! Match your load, read the resulting L/C values, then use them to build your fixed L-network. Or, knowing the L/C values you can determine R and X of the load impedance. StickyTuneTM mode gives you one-hand tuning by locking the TUNE button -- just transmit to tune regardless of SWR. Has audio SWR meter and audio feed back. Competing products don’t. Built-in 50 MHz frequency counter. Its built-in radio interface lets you use a simple wire cable to compatible rigs. Others require a cable with expensive electronics. Binding post for random wire. Self-test. Highly efficient L-network. 10 Amp/1000V relays, RF duty silver mica capacitors. 61/2 Wx23/4Hx71/2D in. 2.4 lbs. 12-15 VDC/ 1Amp or 110 VAC with MFJ-1316, $19.95.

MFJ 1798

Operate 10 bands -- 75/80, 40, 30, 20, 17, 15, 12, 10, 6 and 2 Meters with this MFJ-1798 vertical antenna and get full size performance with no ground or radials! Full size performance gives high efficiency for more power radiated. Results? Stronger signals and more Q-5 QSOs. Full size performance also gives you exceptionally wide bandwidths so you can use more of you hard earned frequencies. Full size performance is achieved using separate full size radiators for 2-20 Meters and highly efficient end loading for 30, 40, 75/80 Meters. Get very low radiation angle for exciting DX, automatic bandswitching, omni-directional coverage, low SWR. Handles 1500 Watts PEP SSB. MFJs unique Elevated Top Feed elevates the feedpoint all the ay to the top of the antenna. It puts the maximum radiation point high up in the clear where it does the most good -- your signal gets out even if youre ground mounted. Its easy to tune because adjusting one band has minimum effect on the resonant frequencies of other bands. Self-supporting and just 20 feet tall, the MFJ-1798 mounts easily from ground level to tower top -- small lots, backyards, apartments, condos, roofs, tower mounts. Separate full size quarter wave radiators are used on 20, 17, 15, 12, 10 and 2 meters. On 6 Meters, the 17 Meter radiator becomes a 3/4 wave radiator. The active radiator works as a stub to decouple everything beyond it. In phase antenna current flows in all parallel radiators. This forms a very large equivalent radiator and gives you incredible bandwidths. Radiator stubs provide automatic bandswitching -- absolutely no loss due to loading coils or traps. On 30,40, 75/80 Meters, end loading -- the most efficient form of loading -- gives you highly efficient performance, excellent bandwidth, low angle radiation and automatic bandswitching. MFJs unique Frequency Adaptive L-Network provides automatic impedance matching for lowest SWR on these low bands. Tuning to your favorite part of these bands is simple and is done at the bottom of the antenna. you dont need a ground or radials because an effective counterpoise thats 12 feet across gives you excellent ground isolation. You can mount it from ground level to roof top and get awesome performance. The feedline is decoupled and isolated from the antenna with MFJs exclusive AirCore high power current balun. Its wound with Teflon coax and cant saturate, no matter how high you power. Incredibly strong solid fiberglass rod and large diameter 6061 T-6 aircraft strength aluminum tubing is in the main structure. Efficient high-Q coils are wound on tough low loss fiberglass forms using highly weather resistant Teflon covered wires.
