AW07A SWR HF/VHF/UHF Antenna Analyzer
SKU: 28-020-708

Availability: In stock

The AW07A SWR analyzer is a compact battery powered RF impedance analyzer.
The AW07A also measure RF impedances between a few ohms and several hundred ohms.
The AW07A also functions as a non-precision signal source and frequency counter.

AW07A antenna analyzer is a compact battery powered RF impedance analyzer. It can test the SWR status of your antenna, measure the impedance and reactance component and help you to solve antenna problems. This unit combines six basic parts: a variable oscillator, frequency counter, independent oscillator, 50 ohm RF bridge detector, an A-D converter, and microcontroller. This compact product was built to feed the need for the solid contruction and field test. The operating frequency range of this unit goes from HF, and extends up to 485MHz. The operating frequency range of this unit extends from 1.8 to 66 MHz in six overlapping bands, and includes SWR measurements on 87-190MHz, 225-485MHz.

Looks capable
The Analyzer looks very capable but DOES NOT ship with a manua. Due to a lack of manual (the V1.6 I found online) is so inaccurate it does not cover basic how-to-use-it features well at all. You better have a very intuitive finger to discover how to operate.

First, the battery-ext power jumper is not well explained and actually should be a mounted slide switch. Both batteries should be able to be connected letting the slide-jumper switch to determine power! Rather than having to unscrew 4 small screws every time you want to switch power method. V1.6 manual calls for 8xAA, but the Analyzer only has a 4xAA battery holder.

Besides the weird uncovered power issues the lack of a manual on how to operate it is the only big negative I have. I've not actually performed measurements at this time - just got it yesterday.

But it does look more capable than my MFJ-269.

good quality, does the job well, good value
It is well made, nice quality, has a heavy gauge metal case, a "N" connector for RF in/out, and has a display back light. On the 70cm range it does SWR only, all other ranges you get the Impedance and the SWR. Overall good quality, does the job well, good value.
Review by Bobby /
good for the price
very handy for building antennas, i have yet to use it for capacitance and inductance as i dont know how to do that so if anyone out there can tell me i would be very greatfull . i have used it for tuneing antennas and boy does it save a lot of time. the instruction manual is poor and basic.
Review by Miui /
A lot of capability for the money
Works as advertised. Is well constructed except for the internal battery housing. Does not calculate the sign of jX. Was pretty accurate in measuring resistive loads. Freq knob is backwards: Freq goes up with CCW turn. Also output is noisy when tuning but settles down when stopped. Tuning resolution was a bit low when trying to measure a magnetic loop with narrow resonance.
