Coaxial Cable like RG58 and Connector as per your need. Deze werkt zeer leuk, en zeer makkelijk te bouwen en licht in gewicht en goedkoop. Again, try to keep it aligned with the holes you’ve already drilled so everything comes out straight at the end. Pedro EB4DKA and I usually have long conversations and we always have the same idea on the brain, to make the ham satellites easier to work so more people will be able to work them. To be honest, it is possible but you need skill to pick the modulations up the noise, aiming the antenna, changing the frequency and avoiding going mad.

Satellite Antenna Tips – Tips that may be of help with the most important part of an amateur ra Mark two points of Simon, thanks for the update, I’m reading your IOio page now: So, What’s in the Box? This entry was posted in Equipment. How all of us know the difficult thing is to receive the downlink because the satellites usually transmit with power out between 50mWatts and mWatts with changing polarization and up to Km far away.

Make two 90 degree bends in it at 4. The advantage is that if you take all things apart to be transported it needs little room, so we can put it away in a suitcase to travel by plane or to be sent by mail.

Any need for a duplexer? Jones said… Any need for a duplexer? Hamvention Awards — March 20, No comments. I was just going to say what Rob said: The driven element is a rectangle, 4.

Rather than taking one 36″ rod and adding 3. Extra elaments makes it narrow banded and requires it to be aimed spot on.


The IOio Antenna

So the result was excellent and I just keep turning the antenna in the the approaching VO Satellite’s direction at the moment before the SAT is in range. The FM LEO satellites are one channel device, so we must not take much time than necessary to make a contact. The following frequencies are exclusively for satellite use: After this is done, drill the holes at the marked points on the wooden dowel.

Hier wat informatie wat ik over de CJU tegen kwam op internet. Compass antenba finding direction and skills to use a compass.

Building an IOio satellite antenna

I am looking forward to listening to you soon! Nick bodged it together by tying it on with a piece of desoldering braid, and then soldering the braid iooi the element.

Being a swl, I cannot transmit but I gave this antenna to a fellow ham and he checked the swr anteenna this antenna and we were amazed to get swr under 1: E-mailadres verplicht Adres wordt niet getoond. I used the inner diameter of the perch and it was perfect.

So we became again searching for a linear polarized UHF yagui, because if we work with a hand held antenna, to install a circular polarized one is a nonsense.

Let me know when and I will be listening by. When I told Sntenna 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 xntenna relation to the stuff it was built. Antennas For Easy Satellites.

I would not be able to say which system works better, the only difference is being sitting in the driver seat or in my shack. The scale is 1 – 10, with 1 being poor and 10 being excellent. We were browsing the Net searching for a high gain UHF antenna to be attached directly to the HT, but we only found whip antennas that we have just tested. Your email address will not be published. And then I came to know that I am not having a regulated 12v po…. 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.


As you can see IOIO contain two separate loops for vhf and uhf so this antenna needs a duplexer so that we can connect only one handy radio to it otherwise we need to connect two separate radio, one for rx and one for tx. This antenna ready to work is 1. We were s earching around for some stuff suitable but we did not find it, so I talked about it with my father EA4ABV who apart from ham he enjoys raising canaries, and told me wait, perhaps the plastic stick where the canaries perch on in the canary jails has this measurement.

But it must be small enough to be directly attached to an HT. My wish was to arouse your curiosity about the amazing world of ham satellites. 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.

Hope this is of help Dave, all the best with your new setup.

I build one very SOON! Steps for making the Uhf part.

IOio Antenna

Now solder each short side onto one end of the piece you installed earlier, making one large rectangle! You should now have a nice straight rectangle; bend the ends out 90 degrees, parallel with the short sides, so that there is about a 1″ gap between them.

I have fitted the angleometer: Satellite tracking antenna – A rugged motorized satellite antenna tracking system for construction As with the MHz driven element, bend out the open ends of this rectangle 90 degrees, and then drill slots in the PVC for them to clip into. Simon, sorrt that you didn’t find the time to answer my email. The MK I Version in action.
