Announcing: EggNOGS!

EggNOGS is available now!

What is EggNOGS?

EggNOGS is a kit that helps you build an Egg Beater antenna, for working and listening to satellites such as on the SatNOGS network. Hence: EggNOGS.

A typical Egg Beater II antenna, built using EggNOGS.

Why is EggNOGS?

The difficult part of an Egg Beater build (or any quadrature fed antenna) is the 90 degree phase shift between the two aerial loops. It is best done with 100 ohm, balanced, shielded feed line, which is difficult to come by (understatement.)

EggNOGS uses a PCB to make its own 100 ohm, balanced, shielded transmissions line phasing loop.

What comes with EggNOGS?

EggNOGS comes as a kit with all the “unique” parts, the parts you can’t get at the local hardware store:

  • Circuit boards, including the band-specific phasing board.
  • Pre-drilled 2 inch/50mm PVC cap.
  • Common mode current choke: RG316 and BN-43-3312 ferrite core.
  • Feed point RF connector. SMA by default, BNC and Type-F are available.
  • Stainless steel hardware. (Ok, you can get this at the hardware store. We include it anyway.)

Here’s a quick tour of the parts that come in the EggNOGS kit.

And here’s an amazing video from Bob (Bård) Bjerke Johannessen showing the assembly of an EggNOGS antenna:

What DOESN’T come with EggNOGS?

You supply all the parts you can get at your local hardware store:

  • Aerial loop material, such as solid core copper wire, aluminum strap, etc.
  • 2 inch/50mm PVC pipe as a mast.
  • Feed line, radio, etc.

What ELSE is EggNOGS?

COMING SOON: AmpNOGS

An inline transmit capable LNA for use with EggNOGS (or any antenna.)

COMING SOON: TeaNOGS

A bias-T injector with PTT control for AmpNOGS, if your radio can’t remove bias power on transmit.
