Terms of Use

Last updated: October 25, 2026

These terms apply to your use of ac8gy.com, the Antenna & SDR Projects website. By using the site you agree to them.

What the site is

Antenna & SDR Projects is an independent site of DIY amateur-radio and amateur-astronomy projects. Many project pages were first published around 2010 and 2011 by amateur station AC8GY and are kept as an archive; this site is not run by him. Dates on those pages describe when a note was written, not a promise that a part, program or link is still available.

Not professional advice

Nothing here is professional engineering advice, a certified design or a complete construction manual. Read the disclaimer before you build anything. You are responsible for electrical safety, RF-exposure limits and the conditions of your own licence.

Content and rights

Archived project text, drawings and photographs are credited to their original author, amateur station AC8GY. Newer pages belong to Antenna & SDR Projects. You may read them, print a copy for your own use and link to any page. Please do not copy pages onto another site. If you hold rights in any material here and want it changed or removed, write to contact@ac8gy.com.

Acceptable use

Do not attempt to break or overload the site, and do not use it to send unlawful or abusive messages.

Other websites and ads

Links and any advertisements lead to sites we do not control. A link or an ad is not an endorsement. Advertising cookies are described in the privacy policy.

No warranty

The site is provided as-is. Older pages can contain outdated measurements, discontinued parts or moved software. To the fullest extent allowed by law, we are not liable for loss or injury from using the site or building a project described here.

Changes

These terms may be updated by posting a new version here with a new date.
