  1. Let's go group, only Wi-Fi is not lived jjjj... the best thing I've found profit size ratio!!... pity not having the measurements http://www.7arrays.com/custom/custom_designs_engineering.htm
  2. The bad thing about this antenna is the F / R, how could it be improved? We could take the design of the active element used by Brian Beezley Author of the Site http://ham-radio.com/k6sti/index.html in your Metric Yagis to improve it? Can someone model it and share the changes?
  3. Here are the .maa file UKW 14 Elemente, DDR-Ausführung.maa has a great profit for its size, especially after being modified by the friend Peter Körner .... stolle_us14.doc
  4. Hello greetings to all ... continued with the subject to not let it cool I found this antenna produced only in the old GRANIA Germany in the 70s and 80s, great gain but very badly distributed throughout the bandwidth we use today (88-108) in those times and in that F / r.
  5. Please someone who uploads the scheme of a good RF amplifier for this band that is well tested
  6. Please upload all the data, I mean gain according to frequency, f / b, etc.
  7. I'm going to try your suggestion, I like it to be 75 ohm and especially the size
  8. You're right, it's big, it was just to test if it could be made smaller and keep the gain high, maybe with a bigger reflector, you are the specialist, thank you very much
  9. simulate this ... but try to give a more contained size and run the frequency towards 98 Mhz and not the 105 Mhz in which the band is centered in this antenna
  10. If that works it would be very good, it has a good size, how did the simulation turn out?
  11. excellent, this is what i mean
  12. Someone who models this antenna for please ...... no idea of the measurements, they have told me that it is very good but I have never been able to get measurements
  13. Friend, I have received stations with that antenna at a distance of 2200 km in New York and 2000 km in Houston Texas, but that happens 1 or 2 times a year at the most, when atmospheric conditions condition the propagation of radio waves, fundamental when DX is done in this band, (which seems to be what happened to our friend Sven) ... but it is not the common thing and less with this type of antenna and with those characteristics. The stations that I listen to the most daily are in that range of 200-250km and let me tell you that even with a signal amplifier and the antenna that I post at the beginning of the post (and which is more powerful than that) it is difficult for me to maintain stability in the signal. I opened this topic to see if something new emerged in the debate and other friends knew of other types of antennas with better characteristics and that were not so gigantic and complicated, something that with 3 meters in size achieves the maximum possible gain that can be squeezed ... .. if not possible there are no problems
  14. Greetings ... I already tried it and it is very good for its size but no, it is not that good, it does not have enough gain and the F / B is not that good either I have stations behind that bother a lot, I need at least 10 db in the whole band, or in large part at least to avoid having to use a signal amplifier, there are solutions, but they are huge monsters so I keep looking for something more ideal. I have reviewed http://www.ham-radio.com excellent site and there are very interesting things but who knows maybe there are better things out there, creative and intelligent people abound in this world.
  15. the size I have always said from the beginning no more than 3 meters
