HF Antenna Analyzer with touch screen controller (2.8" TFT LCD)

Description

HF Antenna Analyzer with touch screen controller
Note:
Casing is optional.
If you are interested please ask for details i.e. price, color, and availability
This Antenna Analyzer uses STM32 board with 2.8" TFT LCD touch screen.  All functions of this Analyzer are controlled by the touch screen. There is an option to change frequency by using an external encoder (included), but this is not necessary as frequency can be changed by touching the screen.
You can select central frequency and frequency span which can be used by this Antenna Analyzer, or your selected frequency set-up can be used by VNA which you can use to test the bandwidth for crystal filters or band filters.
VNA and RF power meter use the second BNC connector on the board, whereas the Antenna Analyzer uses only the first BNC connector.
The Antenna Analyzer also features an RF power meter, which works on HF (30MHz). It was also tested on 200MHz but there is an error of over 5%.  The power meter should work to 500MHz but has not been calibrated for this level.
The package includes the PCB with all required electronics. No other work is required. You only have to connect the power supply (+5V).  On the Antenna Analyzer, there are three mini USB connectors - power supply can be connected to any of them.  This is a stand-alone module, with no PC control required.
You are bidding for the complete Antenna Analyzer, as per the pictures.  Feel free to contact me with any questions.

Most asked questions and answers
Q:
Looks a lot like it's one of the open source analysers... do you have a link for it?
..
what is make/model #?
A:
This analyzer was developed here by Softmark and was not downloaded from anywhere.
Q:
Is there a downloadable instruction manual available. Also on the antenna analyzer
what is the usable frequency range? (I am interested in 135khz)
A:
A c
omprehensive manual and schematic is included.
Setting center frequency starts from 1Hz, span frequency from 300Hz.
For example, it’s easy to set center frequency to 135kHz and span to 10 kHz in setup mode "S."
The analyzer was tested for "R" only - it works.  It was not tested with a real antenna for 135kHz.
Maximum setting for center frequency is ~ 55 MHz
Q:
I see this will go down to 135kHz. How low will it go?
I would like it to setup WWVB receivers on 60 kHz
A
:
Min for Center frequency is 30kHz
...
ie start can be from 15kHz up
