    Tá diskusia je spred 10-tich rokov, vtedy boli ceny určite iné. Neviem ale ktorý drôt vychádza 4,36€/m 🙂

    Určite ale rozdiely sú. Ja najčastejšie používam 2,5 mm Cu lanko s PVC izoláciou. Má to však háčikPVC praská a tak sa do lanka dostane vlhkosť. Rátam však s obmenou každých pár rokov, takže ak zbadám zhoršenie vlastnosti antény, je čas preveriť a vymeniť.

    laa, Joseph!

    Hopefully, over time, support for displaying APs like wtKST will be developed. I consider that a great advantage – i see, that in a few minutes there will be a chance for such a QSO, so I call the given station.

    I do not remember, that someone in OM HA1YA would use the transverter. OM2Y (OM2IB a OM2KI) they use a crystal gate from HA1YA.

    It would certainly like to take that into account as well, what device it will be connected to, see:

    i atenuator a kusok drotu, whether it is possible. I found only http://prntscr.com/SpA9MRIFPZds

    It is questionable, what “Aliases and previous callsigns” it does. Maybe it's not a good practice to want a redirect – if anyone wants to send a QSL for connecting to the original tag, so the redirect could confuse him (i was looking for OM3XYZ, so why i see OM3ABC?). It is probably optimal to have both brands listed in the description of the original one, that you already have OM2ET.

    TNX Vilo and Ron,

     

    at the end a powered antenna like endfed will have high efficiency. It's a very walkable antenna (I tested in the previous QTH). But it's good, to be stretched, for example, from a block of flats, where “stop” against the country. I had it stretched out in the open space and VFka traveled all the way to the facility.

    According to the simulation, it seems, that the maximum current at W5QJR is in the base of the antenna. Simulation with 8x radial in the heel, average conductivity of the earth. It should be a vertical antenna, thus, that part of the antenna is critical to operation. Dimensions should be an advantage, direct power supply by coaxial cable and absence of any loss element in the antenna circuit. It quite resembles inv.L, but where the impedance ratios are different (equally high inv.L has a much lower impedance at the heel). The files are attached.

    According to the possibilities and weather, I would build it and compare it with the used antennas.

    It would not be more appropriate to measure this with a two-tone test? https://om0a.cq.sk/amaterske-radio/ubitx-imd-modifikacie/

    Because if I look, so in the middle I see a strong carrier, it won't “TX Carrier suppression” and others may also generate an oscillator at some rate, which may be related to FM.
