Quadmula Siren F3 SMA Antenna Holder

SMA Antenna and Receiver Antenna Mount for Quadmula Siren F3

Since Quadmula only gives out TBS SMA antenna mount TPU parts, I've decided to design and test out my own. The optional TPU part from Quadmula doesn't even fit the slimmest SMA antenna and it requires the T-plate to secure it on the mount.

With this mount, the inner diameter is set to firmly hold onto a regular SMA connector.

Design Features:

• Antenna holder that actually fits an SMA connector
• T-shaped Receiver antenna holder included

*Stability Arms provide secure and quick mounting whilst reducing weight

• 60% lighter due to theStability Arms
• Weight: 5g, great for sub-250 builds

Notes

• some assembly skill is required
• when prototyping the design, I've found that using a soldering iron to melt out channels for the arms to fold works great
• this iteration resolves the fuss of having to melt the arms

How I Designed This

Securing the Receiver Antenna without zipties

When securing the T-shaped/Immortal T receiver antenna, I find it's best to melt out a channel on either side of the antenna hole with a soldering iron (see image). Then, fit the T-shape in the hole and stick the horizontal shaft on the channels.

Now the photos show that I've slit the hole at the bottom, you DON'T need to do that. It's because I only designed this after I've fit the receiver on the quad. And by that time I'd already heat-shrunk the antenna on the receiver, so the cut is just to allow the antenna to slide in the hole
