Starting on Amateur Radio Satellite is really easy !

Really ? What do I need ?

➜ First, you need a amateur radio license ! If not, you will be abble to listen but not to transmit ! If you want a licence, you have to contact a Radio Club near you to prepare the exam ! In US, take a look at ARRL website !

➜ You need a VHF/UHF radio : It can be a FM handset or a SSB transceiver. You can also receive with a SDR dongle like the Funcube USB dongle.

➜ You need a antenna, for radio, it is recommended :) You will find a specific page about this subject here.

➜ You have to know which satellite on which frequency and at what time you can catch him ! It can be tiresome to hold your antenna in one hand during hours but you don't have to do this ! This website can give you all this informations, you only have to know where you are and to translate this in QTH locator (a 6 caracters long position on all the world that you can find on this website).

➜ What else ? That's almost all. You have a lean how to play with doppler effect which modify frequencies and how to make contact but it is like each time with amateurs radio stations : Listen before to call ! Listening is learning !

Antennas for amateur radio satellites

Portable or at station ?

Depending of your budget and your situation : If you have a perfect environnement, free space around, low horizon at 360 degrees and an unlimited budget to buy antennas, rotors and a huge transceiver, just do it !
If not, ask yourself around you if you can easily access to a high point on a mountain not so far from your house... A portable antenna will be a good solution, even to make distance records (ask Dave KG5CCI who have make record on AO-7 - 7947 km and on FO-29 - 7600 km, he use an arrow antenna on his mountain, it is unbelievably effective !).
However, it can be both : portable and station ! You'll never miss a satellite ! :)


Arrow 146/437-10 antenna is certainly the must have to operate in portable ! Buy one

Elk Antennas produce a 2M/440L5 Dual-Band Antenna which is a periodic antenna Buy one

Build his home made antenna is great ! You can find articles bellow :
Tune in to space with a homemade yagi antenna.

Building the UHF Cheap Yagi for Satellite Communication


➜ Buy motorized crossed yagi antennas solution is the best solution but certainly not the cheaper ! Your choice can be a LEO-Pack Antenna System distributed by Amsat but X-Quad antennas from Wimo have now a great success. For serious game, Crossed LFA Antenna are serious players with remote switch polarization and LNAs.

Any vertical antenna can be a solution but you can make QSO on most satellites, it is not really easy because you will fall on QSB but it can be a starting solution...

Built home made omnidirectional antennas for satellites :
This solution is perfect to automatically decode satellite signals but also to make QSOs on all satellites, easy to build and not expensive. You need pvc pipe and aluminum tube, few coaxials cables to do the phasing harness. You will have to build 4 antennas : 2 crossed Moxon for VHF and 2 crossed Moxon for UHF.
If you use aluminium tube with diameter of 4mm you can fold easily the tubes. You can use electric clamp to make the connection.
A is connected to first moxon to the copper core and connected to copper core of the first 75 Ω harness.
B is connected to second moxon to the copper core and connected to copper of the 50 Ω harness.
C is connected to second moxon to the shield and connected to shield of the 50 Ω harness.
D is connected to first moxon to the shield and connected to shield of the first 75 Ω harness.
E is interconnection of to the reflectors.

To help you with the dimensions, you can you the Moxon construction software. My calculations for harness dimensions :
For VHF : 2 X 1/4 75 Ω (TV cable with 0.84 velocity) : 433mm + 1 X 1/4 50 Ω (RG58) : 340mm.
For UHF : 2 X 1/4 75 Ω (TV cable with 0.84 velocity) : 145mm + 1 X 1/4 50 Ω (RG58) : 114mm.
Harness are placed ideally inside PVC tubes.
