Basically everyone who needs reliabel 420-450MHz coverage for drones or RF modules ends up with this style antenna — the 2±1dBi gain and vertical polarization are pretty standard for omni pattern work, and VSWR under 1.8 means you're not wasting power across the band.
We see customers in field testing who run it on fixed-wing drones for telemetry links, and it handles up to 100W continuous no problem, so even bigger setups aren't an issue; the fiberglass build makes it tough against weather, which matters when you've got it mounted outside.
One thing you'll like is that it's not a stock off-the-shelf deal — we usually have blanks, but teh connector or frequency tweaks can add 20 days or so to the timeline (the 420-450MHz range isn't the most common to have pre-tuned stock for).
What it does is just scream reliability for outdoor installations, and the lightning protection is direct ground, so if you're in a storm-prone area that's a nice safety net — but it's not ideal for indoor lab use where you might want a smaller form factor because the fiberglass is about 1.5 meters long or so.
Some buyers go with the N-J connector because it's more for drone sides, but we also do SMA on request, just mention it when you quote so we can add a bit of lead time.
Anyway, check your MOQ if you're under 50 units or so — we usually have stock, but confirm lead time if you need something outside the standdard 2±1dBi gain range.
Our MOQ is typically 100 units for custom builds, but we can accommodate smaller trial orders if you reach out directly. Let us know your volume and we'll work with you.
Lead time is usually 15-20 working days after order confirmation and spec finalization. If you need a rush, we can sometimes push that to 10 days depending on current workload.
Yes, we can include a test report for each batch showing VSWR under 1.8 and gain within 2±1dBi. We don't offer third-party certifications by default, but we can arrange them at an extra cost if required.
Absolutely, we can swap the N-J for SMA, TNC, or other common connectors. Just specify the type when ordering, and we'll adjust the design accordingly.
Keep them in a dry, shaded area between -30°C and +60°C. Avoid stacking heavy items on top to prevent fiberglass damage, and store them horizontally or upright in a secure rack.
