MY HYBRID LFA YAGI OBLONG ANTENNAS FOR 144 MHZ

Is there anyone who did not hear IK3MAC via EME? Well, his 24x23 ele monster antenna system for 144 MHz does the job! There are a few photos of his antenna system available on Internet. You can see the antennas are combined of yagi and loop elements but no details available. I thought it must be worth of investigating.

Playing with a LFA yagi EZNEC file, I changed its last director with a loop element. Surprisingly, the antenna gave approx 0.1 dB more gain, however, I saw its side lobes were better suppressed resulting in lower antenna temperature. Also, horizontal main lobe became wider, and vertical main lobe became narrower...

Changing the next last director was furtherly promissing: stille better and better charactersitics. The feed impedance remained with no change...

This improvement takes place with the next directors, too, but...now its impedance is changing and has to be compensated. Comming close to the radiator, no improvement was possible anymore. Obviously, the reflector, the radiator and the first two to five directors must remain as yagi elements.

I have tried with my own yagi antenna files, but also with the YU7EF and G0KSC antennas. Every antenna gave better characteristics in hybrid form, though I can say that the 200 Ohm feeding system gives a little bit better results than the 50 Ohm system, especially when bandwidth is considered and when antennas are put in stack.

Bellow you can find the list of my hybrid models for 144 MHz. Detailed data can be obtained by clicking on the hyperlink of the particular antenna. The models are listed in order of boom length, where you can find the number of all elements, the number of loop elements, the length in milimetres and the height of these loop (oblong) elements in milimetres, too. This is followed by the antenna performances with no loss (the upper row), and with loss for aluminum in the lower row. Finnaly, the central frequency is given and the lowest and the highest frequency for SWR 1,5.

· every model must cover the whole 144-146 MHz band with SWR less than 1,5,

· every model must have vertical side lobe suppression better than 17 dB (as advised by DL6WU, for good stacking),

· every model has LFA shaped radiator and 200 Ohm impedance (except separately indicated).

LFA radiator has big advantages regarding classic open or folded dipole. It gives much better opportunities for modelling, but also better results because all elements are in line within this configuration.

Not only better characterics are obtained with hybrid antennas. Such antenna can very easily be built for combined horizontal/vertical polarisation, or for circular polarisation. You have just to make another set of vertical yagi elements. Oblong directors by their nature are ready to serve both polarizations. Every antenna model is checked for XPOL in the way that vertical yagi elements are mounted 50 mm back on the boom, behind horizontal yagi elements. No significant differences are found in the vertical antenna characteristics. Just a bit higher gain (the vertical boom is longer for 50 mm), and a bit higher antenna temperature. Also, SWR on the central frequency changes just a litte bit, therefore nothing has to be specially optimized. However, if you want to get the best, just send me a e-mail and I will give you the necessary corrections. Also, if anyone wants to improve his classic style yagi by adding one or more oblong directors – here I am.

Another good advantage of the hybrid antenna is good stacking results. Bellow included is the table showing the QY21105XL4 hybrid in comparison with the EF0211-5B and the G0KSC 11ELKKA, separately for single antenna, and for four antennas stacked for lowest temperature, for highest G/T and for maximum gain

I think the best loop shape is the circle. Modelling with round loops is almost impossible in NEC/EZNEC. The next good shape is the square. I have chosen the rectangle which must be as close as possible to the square in shape.

In the detailed files for a particular antenna, you can see the table with antenna element dimensions. All oblong elements of a particular antenna have the same height, therefore the horizontal side dimension is different and is given in the table, marked DQ1, DQ2.... The complete length of an oblong element is, therefore, 2 x height + 2 x DQ. When building oblong elements, you can bend them with a certain radius, but keeping in mind that bending should not make the complete length extended or shortened.

Keep in mind that the boom correction is not included. For oblongs this correction is not needed, but yagi elements are very sensitive to correct length. Since there are no absolutely precize boom correction formulas, the best way is to avoid the impact of the boom, by mounting elements on isolators at least 10 mm high over the boom. If you realy must mount them not isolated, apply the SM5BSZ formula for boom correction or find data on YU7EF web site.

Regarding LFA radiator: In the detailed info of an antenna you can see De1 and De2 dimension and the distance between them. You have to calculate the total length of the LFA radiator by yourself:

The feeding point is usually placed on De2, check the sketch in the details file.

As mentioned before, just another set of yagi elements have to be placed in the perpendicular plane, 50 mm back on the boom. However, if you want it correct, all elements must cross each other in centerline. Therefore, mounting over the boom is not allowed – elements must pass through the boom, and that means boom correction!.

There is another approach: just the oblong elements are mounted on the metal boom. Since the length of the boom with yagi elements is not too big (2 – 3 mtrs), it is possible to use a good fishing rod for this part of the boom – keeping all elements in centerline.

The next problem that must be solved is: both coaxial cables must be lead beyond reflector, not alongside the boom. The cables must not interfere with both horizontal or vertical radiation zone of antenna. (This applies to antenna mast and holders, too, which have to not be of metal, either).

The table contains some antenna models of the well known modellers: YU7EF and G0KSC so you can quickly get vision of what qualities you can expect. The rows in yellow are G0KSC antennas with the loop elements added by me. Here is the table...
