v3 Xtreem Cross-air 5.8 GHz 10 dBi Long range fpv antenna

Xtreeme Cross-Air V3 — Directional 5.8 GHz FPV Antenna

Every unit measured. Every unit labelled with its own numbers.

The Cross-Air V3 is not sold on a datasheet figure. Each antenna is swept individually on a VNA before it is packed, and the label on your unit shows the exact frequency span it was measured across and the VSWR ceiling it held there — your antenna, not the model average. The V3 builds on the proven V2 with tighter signal characteristics and a tougher build.

Engineered for hostile RF

• Directional, circular polarization — RHCP or LHCP, your choice
• 10 dBi gain, beamwidth up to 120° — long range and technical proximity from the same antenna
• Low axial ratio — this is what holds the picture together when the line of sight goes behind trees, foliage or a wall of pilots. Not a marketing adjective; it's the reason multipath doesn't wreck your feed
• VSWR below 1.3 across nearly the whole Raceband — and in practice most units land well under it. A Cross-Air that doesn't reach 1.2 is never sold; it goes out as a freebie instead

Built, not assembled

• Connector soldered, not crimped — and fitting it is the final tuning step, not an afterthought. That is precisely why the numbers on your label read the way they do
• Semi-rigid cable holds any angle you bend it to and stays there
• ~40 mm cable — shorter than V2 — sits close to the goggles instead of levering off them
• Made in Poland, on our own jigs, one unit at a time

Order two and we'll match them

Whenever an order contains more than one antenna, we tune them to each other. Every time, as standard, at no extra cost — that's simply how we ship multi-antenna orders.

So add a second Cross-Air, or pair it with one of our omnis for full diversity coverage. You get a set that actually works as a set, instead of two antennas that merely happen to share a band.

Need a specific frequency instead of our standard 5800 MHz centre (effective 5650–5930 MHz)? We tune anywhere across 5640–5940 MHz — see Custom Tuning in our shop. Returning customers get one free retune per order: just quote the range printed on your existing antenna's label and we'll match the new unit to it.

Compatibility

Analog and digital alike — DJI, ImmersionRC, Boscam, Skyzone, Aomway, Caddx, Walksnail.

Who it's for

• Racers who need penetration through course obstacles and gate clutter
• Long-range pilots who want measured, provable signal quality — not a claimed one
• Anyone moving up from omni-directionals and wanting the gain without losing usable beamwidth
