Does anyone know what the theory behind these antennas is? all i can seem to see is that the radiator is about a full wave – but what about the. Ok, I know I just posted about Moxon antennas, but doing an image search for moxon antennas led me to the CJU antenna. Amateur Radio,Projects,Antenna Designs, Double Quad Beam,2m & 70cm SSB, Ham Satellites I found the 70cm CJU or IO works well on mhz as well.

This kind of behaviour interferes with satellite abtenna making them more difficult that they are. Then we only had a way, to improve the antenna. Glad to hear that the CJU lives up to its expectations. The scale is 1 – 10, antwnna 1 being poor and 10 being excellent. Do you enjoy making your own equipment or antennas? Dus was ik snel klaar.

CJU or IOIO Antenna for 70cm

When I told Pedro what kind of stuff I have used to build the antenna we were burst out laughing for a while and he quickly baptized the antenna as the Canary Jail Umbrella antenna in relation to the stuff it was built. I was surprised at his comments so I decided to build another one and try my luck.

Glad to see that you have made cjj. Door verder te gaan op deze website, ga je akkoord met het gebruik hiervan. The Arrow antenna has seven elements in a 1. I just got my ticket a week ago and have had a blast so far though I haven’t talked to anybody yet. Coax kabel eraan …Antennemeter erop, en over de gehele 70cm goed. The FM LEO satellites are one channel device, so we must not take much time than necessary to make a contact.


I think the latter is to the centre of the wire,if you are using 2 mm wire.

CJU Antenna

Then we were looking around and we analyzed the antennas we usually use to receive UHF signal with enough gain. Anyway, I built the CJU 70cm antenna and was surprised about something. I’ll shorten it first to see how that works.

KD8KSN QRV: The CJU Antenna

We must take a lime flower tee before pushing the PTT the first time, because when we listen to our self modulation you will get nervous and you will not be able to say your locator and report signal properly which are the minimal dates to validate the contact. This antenna has a bit less gain than the seven elements Arrow antenna because the IOio antenna is equivalent to a four elements yagui antenna, but we have experienced that it has enough gain to receive the satellites comfortably.

My wish was to arouse your curiosity about the amazing world of ham satellites. De CJU antenna voor 70cm word veel gebruikt voor satelliet verbindingen.

Regarding AO51,on the antennw topic,I have put a few pass times. I think that with this tool attached to an HT in your left hand and with the microphone of your mobile station in your right hand you will make satellite contacts successfully.

Would it also work if the radiator was mounted at right angles to the reflector. Also a couple of sites for pass times.


CJU antenna – Transmission1

As included in your reply on the Work-Sat YahooGroup, see if these references help I have not built one. Deze werkt zeer leuk, en zeer makkelijk te bouwen en licht in gewicht en goedkoop. Who is online Users browsing this forum: We must give other hams anttenna opportunity to make more contacts. Eerst heb ik de maten op een plaat-hout gezet daarop wat schroeven voor geleiding en buigen.

The DXZone is the largest human created and maintained library of web sites dedicated to Amateur Radio, currently lists But somebody could say that a HF antenn is simpler to work, I disagree with this opinion because if you have a PC which aims the antennas at the moving satellite and changes the frequency, we only must talk, our reliable friend the PC will anteenna the hard work.

Ik hoorde Pa0Ete op de ingang en draaide wat rond en je heb gelijk de juiste richting. To sum up, we must try to improve the UHF received signals. It is a pity to listen to hams, specially from antebna country, through the satellites. It sounds like a problem with the reflector size or spacing When somebody uses these frequencies because they do not know the rules we must try to explain them, we must always be polite.
