Great first antenna analyzer

Reviewed in the United States on March 30, 2019

Verified Purchase

I'm just getting re-started into amateur radio at the very young age of 65. Antennas have always seemed like black magic to me. This little gadget is great for someone who is even mildly technical. I soldered the included headers onto the board and mated it with a little Arduino Uno clone in which I had burned the serial repeater software (available on the RigExpert website). After attaching it to my laptop with a USB cable and then to my antenna, I was getting measurements from using RigExpert's Antscope software within minutes. It told me that my Buddipole portable antenna was not quite setup correctly for 40 meters. Making even tiny length changes (e.g. 1") in the antenna whip extensions changes the frequency impedence characteristics in very measurable ways. Scanning the whole frequency range from 0-30MHz is enlightening on this simple dipole. This little tool is going to very useful and a whole lot of fun in coming years.

If I get really ambitious, I may even come up with a sketch or two on the Arduino or possibly mate it with a Raspberry Pi with and a tiny LCD to make portable tool for field use.

The open source Antscope2 software is out and the source code has been modified to support the new AA-30.ZERO board, but I haven't seen a bundled installation package for Windows, yet. For those with a minor amount of ambition, you could download the Antscrope2 source from GitHub and compile it on your local PC.

Again, this board is easy to use, well made and pretty accurate according to an ARRL QST article from August 2018. There are even silk screened markings of the board into discrete logical sections (e.g. mixer, oscillator, amplifier).

Very good value for the right use

100Khz - 30MHz is useful for pre-compliance EMC testing and Tesla coil testing.

The free software is very good.

I would like to see some real world examples of why they made it in the arduino form factor.

Product came in a small brown paper-board box. Pin headers were separate from the board in a plastic bag. In my application, I wanted a small analyzer that I could use in the radio room for testing homebrew and purchased antennas. I purchased the DSD Tech USB to TTL adapter https://www.amazon.ca/dp/B078W5L8W1/ref=cm_sw_em_r_mt_dp_U_aIvtDb2JV9DY9 (came 2 to a package) and this combination worked very well for my purposes. Software from RigExpert (download here: https://rigexpert.com/products/software/antscope/) was easy to configure and use.
The software really makes this device sing! You can define how many measurement points for the range you are testing. This allows you to provide a low resolution scan to do initial testing and tuning of an antenna. As you "hone in" on the frequency range of interest, you can narrow the scope of the scan and increase the measurement points for better resolution. I found scanning a single amateur radio band with 500 points gave excellent results without taking an excessively long time to complete. (if you have the time, more points will give you a much more detailed report, but at 1000 points, you may have to wait a few minutes to complete.
The board itself is professionally made and of the highest quality. Surface mount elements are positioned accurately and solder connections are as excellent. The SMA connection seems solid and I don't worry too much about it, but I also purchased a short (6 inch) SMA to UHF adapter to reduce the direct strain on this connector. I highly recommend one of these with this board. Similar product here: https://www.amazon.com/dp/B07CPVXYBN/ref=cm_sw_em_r_mt_dp_U_lRvtDbS6VAV0A
I haven't found an enclosure for this (yet) but am thinking about an Altoids Tin (yes it will fit). Will post photos when complete.

works well and fairly intuitive if your are familiar with VNAs

Just got this and hooked it up. took a star away on the feature ratings as it does not come with any form of instruction. had to go to the website and look up how to connect it, also had to remember the old RS-232 paradox TX connects to RX and RX connects to TX. most people (me included) are used to things being labeled where a goes to a and b goes to b not the reverse. The software (AntScope2) was a little bothersome as well. It would only connect to the hard ware after I had connected the unit to the computer let it be found by Win10, then check what com port it came up as in device manager, bring up the software and under settings change from "Auto" detect to "Manual" and select the correct com port with the little up/dn arrow buttons, then set the detect back to "Auto" and close and reopen the software. Once I did this the software found it and worked fine just a bit odd to me though. but now it runs fine.
I am running the newer Latte Panda (w/Windows10) and so there may be some nubs there. never know.
will give updates as time goes by.

Great product Great price Unable to verify accuracy but as with other RigExpert devices they work very well

Wish their was more community involvement with Arduino board and incorporating keypad and lcd screen

Great deal, great tool

Reviewed in the United States on February 17, 2020

Verified Purchase

Amazing deal for a great antenna analyzer sans the screen and buttons. I prefer using the computer to plot the antenna data anyhow so this works great. Fit nicely into a Coleman waterproof wallet box. Used a bulkhead connector for the UHF and adapter to neck down to SMA. The USB to serial interface plugged right into the board after soldering the pins. Only gave 4 stars for ease of use as it came with no directions and had to visit the website for info.
