Why do the AEROLINK links use the 1.4 GHz band?

Lower frequencies propagate better around terrain and vegetation and are less congested than 2.4 GHz/5.8 GHz, where consumer Wi-Fi lives. All AEROLINK series links operate on 1.4 GHz with custom frequency bands supported — which also matters for regulatory approval in your country.

Can I use these links in my country?

The links support custom frequency bands so they can be tuned to what your regulator licenses. Check your local rules for telemetry/video bands before ordering; we ship the hardware configured to the band you specify on the order.

How do I get a quotation, and how long is it valid?

Send the model, quantity and destination country — the quotation comes back with the EXW unit price, packing details and lead time, and stays valid for 14 days. Links are quoted per set (MOQ 1 SET).

How to Choose a Video & Data Link: Range, Nodes and Frequency Bands

Every data link datasheet leads with the same number: range. It is also the number that tells you least on its own. A 300 km point-to-point link, a 30 km mesh network and a 100 km data-only pipeline are three different tools that happen to be measured the same way, and the wrong one is useless at any distance.

This is the buyer's walk-through of our AEROLINK series — the three families, the decisions that separate them, and the questions to answer before you ask for a quotation.

The three families, in one table

The AEROLINK line splits into three series, all operating on 1.4 GHz (custom bands supported) with real-time spectrum sensing:

Series	Example	Ground-to-air range	Networking	Built for
Anti-Interference Video & Data Link	HK-T46	300 km	3-node networking	Long-range video + data where the interference environment is hostile
MESH Video & Data Link	HK-M27	30 km	MESH, up to 128 nodes	Multi-platform teams, relay chains, beyond-line-of-sight by hopping
Long-Range Data Link	HK-S30	100 km	Up to 128 nodes	Data-heavy missions where telemetry and payload data matter more than live video

All three share the same foundation: 1.4 GHz operation, real-time spectrum sensing with dynamic frequency hopping, network-port and serial interfaces, and configurations for UAV, USV, UGV, robotic platforms, maritime and mountain-relay use.

Decision 1: How many nodes talk at once?

If the answer is "one aircraft, one ground station," a point-to-point anti-interference link is the efficient answer — the T46's job is to hold a clean 300 km channel while everything else on the spectrum fights for attention.

If the answer is "a patrol line, a relay chain, or several platforms that need to see each other's data," you are in MESH territory. The HK-M27 builds a self-healing network of up to 128 nodes across 30 km per hop: every node extends the mesh, so range accumulates with deployment rather than with transmitter power.

Between those, the S30 family keeps long-range data moving — 100 km class — while still supporting large network configurations, which suits UGV convoys and sensor backhaul more than live HD video.

Decision 2: What does the interference environment look like?

Spectrum sensing with dynamic frequency hopping is the AEROLINK signature: the link continuously maps the noise floor and steps around it. How much of that capability you actually need depends on where you fly:

Rural powerline and agriculture: modest congestion; the hopping protects against the occasional farm router and the harvest-season surge.
Urban and industrial sites: dense 2.4/5.8 GHz traffic is exactly why the series sits on 1.4 GHz — a band consumer devices mostly ignore.
Border, maritime and mountain relay: distance plus terrain, where the anti-interference series' 300 km ground-to-air rating and custom bands earn their keep.

Decision 3: Video or data — and how much of each?

Live HD video is expensive in bandwidth; telemetry and payload data are cheap. The T46 carries video and data together at long range. The S30 leans data-first. Before comparing datasheets, write down what the ground station actually needs to see in real time — often the honest answer shrinks the bandwidth requirement and the price with it.

Decision 4: What platform is under the antenna?

The same link family serves UAV, USV, UGV and quadruped platforms — but weight, power and antenna placement change what is practical. A tracked UGV on a 10 km/h patrol loop has very different antenna geometry from a VTOL fixed-wing at 20 m/s. Tell us the platform and the mission radius; the recommendation follows from those two facts more than from any datasheet comparison.

The frequency-band question

All three series ship on 1.4 GHz with custom frequency bands supported. Two practical consequences:

Congestion: 1.4 GHz sits below the consumer bands, which is a real anti-interference advantage in towns and industrial zones.
Regulation: every country treats these bands differently. The hardware tunes to the band you specify — check what your regulator licenses before ordering, and put the band on the purchase order so the units arrive configured.

Range math, honestly

Ground-to-air range assumes altitude. A 300 km rating is a line-of-sight number between an airborne platform and a ground station with clear geometry; a UGV at 2 m antenna height talking to another UGV at 2 m will see a fraction of it. If your mission is surface-to-surface, the MESH series' hop-by-hop extension is usually worth more than a big point-to-point number — that is the difference between the families that no datasheet comparison shows.

How we quote it

Links are quoted per set (MOQ 1 SET) with EXW pricing from Hong Kong, and every quotation is valid for 14 days. Because configurations vary — band, interfaces, antennas — many link models are priced on request rather than listed. Send the platform, the mission radius and the destination country, and the quotation comes back with the configuration written down.
