If you purchased a kit, the instructions are here:
We support our products primarily via email, but also via the phone. We try to answer email quickly and that is generally the best avenue for questions. Please visit our Frequently Asked Question pages first to see if your question is already answered.
If your kit is short parts or you have questions about the parts see the Contacts page and drop us an email.
If you have problems with our Pneumatic Antenna Launchers see the Launcher Manual and the Launcher Troubleshooting FAQ for help. If that is not sufficient please contact us.
