Autek Research QF-1, Autek Research QF-1A, Autek Research RF-1Įach is several years old, and while I don’t believe that I have ever dropped or abused them, they have been well used. As before, the sign of the reactance was taken from the computed data. For consistency sake, use an external power supply, or fresh batteries.
#Autek va1 for sale portable#
The initial use of the portable antenna analyzer was to measure SWR.ĭan and I worked independently, and we happened to exchange emails after I had finished my page, but before the compendium was available. To maintain lowest distortion you should load it down as little as possible. These features alone makes it unique at its price. Autek Research RF AnalystĪll of the impedance values will repeat every half wavelength. Sale HP 5258A Sensitive Prescaler 50.00 40.00 Kachina Power Probe.

I connected these three parts into several series and tf-1 combinations in order to create a set of expected values. Autek Research WM-1 Computing Meter 75.00. There are so many competing analyzers on the market now that they may have thrown the big switch. I did get a WM-1 meter from them last Fall - just before they pulled the plug on that product. I bought the RF-1 Analyst for general use several years ago. Auteks been around a long time, but their customer service was never a strong point. For my recent applications, that would be very helpful. Autek Research, PO Box 7556, Wesley Chapel, FL 33544 USA. Autek Research has some minor quality issues that need to be addressed with this line, but all in all Im very pleased with the VA1s abilities and performance. The is somewhat more expensive than the B. The VA1 is a good tool that makes understanding an antenna system come alive. This is the opposite test to what was performed in the previous section, where pure resistances were measured. We adjust it by connecting r-f1 series-tuned circuit, similar to Fig.

But any distortion on the sine wave increases the SWR.ĬWNA SYBEX PDF AUTEK RESEARCH VA1-RF1-RF5 RF ANALYST Product Reviews I supplied the reactance sign in the and CIA-HF columns, since the devices do not indicate the sign.

It wasn’t designed as a VFO.Īntenna reactance and capacitance measurements would put some professional equipment to shame. Took it home and fired it up with a precision 50 ohm resistor. Ahtek the purposes of future graphs related to the 2.

I then used the Lowband software to compute the complex impedance at the input of the cable when the load was set to various resistances. The following graph displays the recorded data when the frequency was swept from 2 through 29 MHz, and the CIA-HF was connected to the test coax with a That data came from a web site that sells that particular autej. The following graph displays the recorded data when the frequency was swept from 2 through 29 MHz, and the RF-1 was connected to the test coax with a For an SWR of 2, the reflection coefficient is 0. It works well and is great for analysing antennas in the field.įull adjustment and calibration requires unsoldering a board. Hi, I have for sale one used Autek Research model RF-1 antenna analyser.
