Description. The MLA-ER (10) is an unique magnetic loop antenna for the 10 m amateur radio band. The antenna is built from the concept of MLA-ER, which originally had relatively difficult tuning, the tuning was simplified in MLA-ER (10) to the extent that the antenna can be well tuned using a SWR meter. The idea behind tuning can be seen in the.
This could be very useful e g for automatic antenna tuning via some script and a electronically modifiable antenna and stuff like that. When installing the application package via pip, a python module that provides tools for using the nanovna-saver calibration and touchstone export and a class that controls the nanoVNA could be provided to be.

Our coaxial cables are 50 ohms, our SWR meters work at 50 ohms, the nanoVNA works at 50 ohm, the antenna tuners convert everything to 50 ohms and so my receiver also has a input impedance of 50 ohms. But is that really so? Measuring it is a nice job for the nanoVNA. The measurement charts presented in this article were created with nanoSAVER.

Consider recalibrating your vna across the band 1-3GHz to see if you can see a S11 resonance at a different frequency to your expected 2.4GHz.I suspect that your meandered antenna lines are too close to each other and you are getting unwanted coupling between these parallel sections of the antenna which is maybe de-tuning your antenna.If the resonance is too low ....

The finished Cobweb in the air. It’s essentially a multi-band fan dipole, but wrapped around fiberglass spreaders in a square arrangement, this means I can have access to 7 bands (20m, 17m, 15m, 12m, 10m, 6m and even 4m), with only a width of 2.7m on each side. It’s also omni-directional, which saves the hassle of a rotator.

Re: 433Mhz Antenna tuning. Seems a little short to me for a quarter wave 300/433 =0.69284 Meter wave length a quarter of that is 0.1732. So you may need to make it longer for better results, I have found that cutting to calculated lengths for aerials normally gives very good results straight off for a fixed frequency.

A Magnetic Loop Antenna is basically just a resonant circuit using an oversized inductor and an adjustable capacitor.. If the inductor has a circumference of much less than, say, 1/10 th of a wavelength, then the efficiency of the antenna will suffer. If the inductor circumference approaches ¼ of a wavelength or more then the antenna would more accurately be.

HF VHF UHF VNA Vector NanoVNA-F 4.3" Network Analyzer Kit with Glass Fiber Case - $131.47. FOR SALE! Description HF VHF UHF VNA Vector Network Analyzer Kit. My MFJ-259B antenna analyzer output is 8 dBm. For repeater duplexers, the receiver’s impedance must match the duplexer’s 50 ohm impedance. I measured the NonoVNA’s sweep output level at 146 MHz’s and the level was -17.76 dBm. This is a safe level for any receiver, so the NanoVNA can be used to measure a receiver’s input (Z).

With the popularity of the nanoVNA, the matter of optimisation of antenna systems comes up and the hoary chestnuts of ham radio are trotted out yet again. Having skimmed a presentation published on the net, an interesting example is presented of an 80m half wave centre dipole with feed line and various plots from the nanoVNA used to illustrate. This new Antenna design has been specifically tuned to operate with peak performance over only the frequency band of interest to USA/Canada Helium Hotspot operators – the US915 & AU915 frequency band. Most commercially available Helium Hotspot Antenna designs available today are designed to be universal – meaning that the one product has.
