LP-100A Digital Vector Wattmeter
Everything you need for critical station monitoring, tuning and protection on one screen. No other meter has dual bargraphs, OR a graphic display with solid bargraphs, OR bargraph with 90 bars for fine tuning of Power and SWR, OR an SWR alarm with snooze mode, OR a “sticky” bar for graphic peak hold indication… let alone having them all on one screen! This is by far the best display for tuning a manual tuner, without having to change display mode for normal operation. It is also the only meter with 11 bands of frequency indexed NIST traceable calibration points using a built-in frequency counter.
Plus, the LP-100A has additional modes no other wattmeter has when you desire them… vector impedance, dBm/RL, calibrated field strength and compression ratio.
Dual Coupler Option Two couplers… one LP-100A… auto-sensing… perfect for SO2R. Better than “paralleled” couplers because the couplers are isolated from each other, and each has its own Calibration table.

LP-100A Features & Specs

* Dual Coupler Option. Allows one LP-100A to use two couplers, with auto-sensing and switching to the active coupler.
Great for SO2R operation or when your transmit paths are different for HF and 6m
* Several new menus for additional customization of user preferences
* LP-100A now integrated with N4PY software
* Graphic VFD display with high contrast non-glare neutral density filter
* Front panel power switch
* Large scrolling call sign screen saver
* Setup screen for call sign entry
* Setup screen for display brightness
* Setup screen for screen saver timers
* Dual 40MHz Processors
* Per-band power calibration, user adjustable in 0.1% steps
* Frequency counter – user adjustable per-band corrections of all parameters.
* Only meter with Z, R, |X|, Phase display… not affected by local broadcast stations as antenna analyzers can be.
* Super wide autoranging power range of 50 mW to 3000W, 160-6m… perfect for QRPp through QRO
* Optional couplers for 5KW and 10KW. Our 10KW will handle more power and generate much less heat than our competitor’s.
* Only meter with Graphic VFD display. The graphic display allows for a solid bargraph with no gaps, and full screen scrolling screensaver as shown in the shot above with N8LP scrolling.
* Only meter with simultaneous bargraphs for Power and SWR (or Power and Ref Pwr).
* Highest bargraph resolution. 90 segments gives 1% tuning resolution with standard bargraph range settings (adjustable)
* Only meter that has a “sticky” bar to graphically show peak hold point even while bargraph is moving.
* Fast attack bargraph will accurately display a single “dit” at over 100 wpm. Decay adjustable for Fast, Med, Slow.
* Active temperature compensation. Only other meter with this is Alpha.
* True 12-bit A/D converter gives <1W resolution at 2000W. 13.6 bit effective resolution up to 360W.
* Return Loss (RL) display of 0 to 49.9 dB with bargraph
* Separate scale for dBm measurements, +15.0 dBm to +64.0 dBm with bargraph
* Field Strength input covers the range of  -15 dBm to +33 dBm (0.04 mW to 2W)… great for beam pattern and bench measurements
* Peak to Average ratio screen. Allows accurate checking and setting of compression in your speech processor.
* Support within TRX-Manager for direct remote monitoring
* Call sign screen saver – user programmable
* Free Plot program displays SWR, Z, Phase, R+jX (including sign), reflection coefficient, Return Loss and Smith chart.
* SWR alarm with “snooze” mode for antenna tuning. Alarm has LED, PTT relay and audible sounder (which can be easily disabled)
* G4HFQ’s free PolarPlot program works with the LP-100A’s Field Strength mode to provide automatic antenna pattern plotting. See software section of this web page.
* Separate coupler with 50 ohm ports for uncluttered desktop – remotable up to 50′ with appropriate calibration.
* Three autotanging scales with independently adjustable maximums.
* SWR display resolution is .01
* SWR error < .15  (5%) from about 100mW to 3000W, <.05 typical
* Power accuracy is better than 5% at any frequency from ~1W to maximum, 3% typical with NIST traceable factory calibration
* Power display is actual power delivered to the load ( Fwd minus Ref power) or traditional Fwd power.
* SWR Alarm system with set points for Off, 1.5, 2.0. 2.5, 3.0 and user setting. Audible & visual alarm, with PTT loop-thru & adjustable power threshold
* Windows® freeware Virtual Control Panel for software control or remote control.
* Built-in bootloader to allow for firmware upgrades to be downloaded and installed.
* Conforms to FCC Part 15 A & B, ICAS and CE radiated emission limits, tested and verified by accredited lab

MFJ-259C SWR Analyzer

MFJ-269C_L

MFJ-259C 530 KHz – 230 MHz SWR Analyzer
World’s most popular SWR analyzer is super easy-to-use

The famous MFJ-259C gives you a complete picture of your antenna’s performance. You can read your antenna’s SWR and Complex Impedance 530 KHz to 230 MHz continuously with no gaps.

You can read Complex Impedance as series resistance and reactance (R+jX) or as magnitude (Z) and phase (degrees).

Determine velocity factor, coax loss in dB, coax length and distance to a short/open.

Read SWR, return loss and reflection coefficient at any frequency simultaneously.

You can read inductance in uH and capacitance in pF at RF frequencies.

Large easy-to-read two line LCD screen and side-by-side analog meters clearly display your information.

Built-in frequency counter, Ni-MH/Ni-CD charger circuit, battery saver, low battery warning and smooth reduction drive tuning.

Super easy to use! Just set the bandswitch and tune the dial — just like your transceiver. SWR and Complex Impedance are displayed instantly!

Here’s what you can do

Find your antenna’s true resonant frequency. Trim dipoles and verticals.

Adjust your Yagi, quad, loop and other antennas, change antenna spacing and height and watch SWR, resistance and reactance change instantly. You’ll know exactly what to do by simply watching the display.

Perfectly tune critical HF mobile antennas in seconds for super DX — without subjecting your transceiver to high SWR.

Measure your antenna’s 2:1 SWR bandwidth on one band, or analyze multiband performance.

Check SWR outside the ham bands without violating FCC rules.

Take guesswork out of building and adjusting matching networks and baluns.

Accurately measure distance to short or open in failed coax. Measure length of a roll of coax, coax loss, velocity factor and impedance.

Measure inductance, capacitance. Troubleshoot and measure resonant frequency, Q of traps, stubs, transmission lines, chokes, tuned circuits, baluns.

Adjust your antenna tuner for a perfect 1:1 match without creating QRM.

MFJ-259C is a complete ham radio test station with frequency counter, RF signal generator, SWR/Resistance/Reactance/Coax Analyzer, Capacitance/Inductance Meter and much more!

Use 10 AA or Ni-MH batteries (not included) or 110 VAC with optional MFJ-1312D.

Compact 4W x 6 3/4H x 2D inches
