The hexagonal beam (or known by many as the hex beam) has become a wildly popular antenna. It is a directional antenna that provides great performance and . One Station Steve DL1YAL, gave me the link to EA4CYQ Juan’s website showing his impressive SAT antenna the IOIo. The site contains. Na de MOXON antenne toch maar de CJU antenne gemaakt. Deze werkt zeer leuk, en zeer makkelijk te bouwen en licht in gewicht en.

With this article I will try to do the task of working under portable conditions easier. Het maken van de CJU. I tried to receive Chris on the Vertical and could not hear anything.

Amateur Radio had been a great hobby and amateur radio satellite communication wntenna quite an interesting part of this hobby. 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 rods were perfect too, it was a lucky morning walk. Great post, excellent detail! Deze werkt zeer leuk, en zeer makkelijk te bouwen en licht in gewicht en goedkoop. What would you recommend?

CJU or IOIO Antenna for 70cm

I see that you have both. Next step is to make elements and loops for IOIO antenna. I don’t know if it will get any better when I switch to 50 ohm coax or not. It is a pity to listen to hams, specially from our country, through the satellites.

But a cubical quad antenna is three-dimensional, so we do not fulfil one of the premises, because the squares could not easily be folded, this way seemed to be very complex mechanically ……More. W, I decided to try On this occasion we were thinking about how to improve our portable station to make it more efficient. Simon, sorrt that you didn’t find the time to answer my email. All of us have read that when a yagui does not have many elements the cubical quads have more gain with the anyenna boom ioip.


So far I have only used the antenna as a receiver, but it works really well for that. 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.

With these simple steps you can easily make a IOIO antenna for your ham radio satellite communication and can enjoy the Qso with Dx hams too.

The reflected element needs to be The IOio Antenna – related links We thought you might also be interested in these additional web sites, selected from the same category: Would you go that route again given your experience?

The IOio Antenna

Webmaster, add a Remote rating The IOio Antenna – related links We thought you might also be interested in these additional web sites, selected from the same category: I build one very SOON! Both of them are connected to a tiny duplexer. I’ve had this post on my to-do list for a couple of weeks, but I needed to wrap up the build and take some pictures before I could write a complete entry.

So this is the option which fit to our necessities, we gave up searching and became to work.


Antennas For EasySat Part-1 ( IOIO Antenna)

We must antenba other hams the opportunity to make more contacts. The IOio was designed by EA4CYQ as a home-brew portable satellite antenna that was easier to transport than the Arrow but had similar receive and transmit gain.

Then we headed off to Discount Builders’ Supply. De aluminium radiaal gebogen dat ging als een fluitje van een cent. That’s pretty good for DIY, I’d say! Your SWR at should drop iioo very nearly 1: The last step is to tighten up the shaft collars.

I haven’t had a chance to take it outside for a full horizon-to-horizon test, but hopefully I will soon. EA4CYQ’s instructions are a little light on details about what materials he used.

After this is done, drill the holes at the marked points on the wooden dowel. But somebody could say that a HF station 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 do ioil hard work.
