[Moon] 9A9B - Antenna down

[Branimir Antolic - 9A9B]

Hi Serge,
If something was wrong with my TX coax line, it means I will heard a lot of stations, but will not have possibility to advert on me.
I have done few RX measurements, but significantly is that last few years I even didn't recognize/flair Cassiopeia (before it was more than 4,5dB!).
For any circumstances, yes I will change also my power divider (my present one, I bought with ma old antennas, but it had/has some cracks on the body and if I will take new antennas, want to be sure that all components are good, including power divider.
73, Branimir 9a9b

  Branimir, sorry to hear about your antenna being down. I assume you check your TX coax line?? & also your power divider often a source of trouble.
  Here I am using 17EL M2 & they are very good but I know in Europe many good antennas as well like YU7EF not far from your home.
  If I can help you with anything please let me know

    Hello my EME friends,
    After more than 25 years (quarter of century :-)), my antennas are down!
    As you know it was 4 x 16el./H Tonna/F9FT yagi.
    Reason for put it down, last years my echo was not so strong as earlier and during good contest conditions, a usually made one third of QSOs than earlier.
    I am not sure if it was right decision, but I am confused, because my WSVR was all time very good (during transmission - 1KW, only few percent of reflecting power), my preamplifier is correct (around 24dB), so my main concern was that something with my antennas is wrong. Yes, I saw some changes around dipole compartment, but not anything significant.
    My confusion was even more, when I measured VSWRs on every particular antenna and on 3 antennas was around 1:1,2, but only on one was 1:1,5.
    In the same time, during this summer it was minimum 2 direct (unusual) lightning hits and after that something happened with my elevation system, so I have to see what is wrong.
    If I will have successes to repair this, next year I will buy 4 new antennas (again Tonna/17 el. or M2/12 el., will se - suggestion?).
    That's all for me, for know, wish you to have a lot of CV EME fun!
