Agri-tech electronics for Argentina need a satellite-positioning antenna, and only 3 of the 44 rows in the Walsin Technology (Walsin) antenna export cover the GNSS band: one as a range, one as a wider range and one as a single frequency. The export holds 38 antennas and 6 cable or connector rows, and none of the 44 is on our shelf.
Venatech Limited, an authorised Walsin distributor in Hong Kong, wrote this from the Walsin antenna export (44 rows, 44 distinct part numbers) and our stock list as at 23 September 2026. It is for a design or sourcing engineer at an Argentine maker of seeders, sprayers, drones or farm telematics who is looking for an antenna to cross. Every part number is real and every count is ours, re-measured on 10 November 2026. The market statement names its source and the day we fetched it.
What did Infobae report about ERCA’s precision products at Expoagro 2026?
It reported a fertiliser dosing system and a drone. According to an Infobae company feature on 16 March 2026, ERCA used the 20th Expoagro to present Fertisystem, a variable and controlled fertiliser dosing system that integrates with its Linea 7 seeder platform, and an alliance to distribute the EAVISION J-150 agricultural drone nationwide.
Those are the company’s claims in a feature the page cites no independent data for, not ours. The conclusion we draw is ours: variable-rate dosing and autonomous flight both depend on knowing where the machine is, so both carry a positioning receiver and an antenna. We have no relationship with ERCA or any Argentine maker, and we say nothing about what any of them uses or buys.
Which Walsin antennas cover the GNSS band, and what differs?
Three, and no two agree on form. We read all 44 rows of the Walsin antenna export and found 3 that state a band around 1575 MHz: a 1565 to 1606 MHz dipole with an SMA connector, a 1559 to 1609 MHz flexible antenna with an IPEX connector, and a dipole stated only as 1.575 GHz with a reverse SMA connector.
Our brief is ours: a receive antenna for the 1575 MHz band with a connector, on a machine panel or a drone. The reader’s incumbent goes in the last column.
| Walsin part | Description | On shelf 23 Sep 2026 | Match / mismatch with the brief | Your incumbent |
|---|---|---|---|---|
RFDPA141300SMGB701 |
Dipole (N, SMA), 1565 to 1606 MHz, above 2.5 dBi, SMA, 171.8 mm long, 13 mm diameter | No | Match on band (1575 MHz lies inside the stated range); mismatch in a long body | |
RFFPA401410IMGB301 |
Flexible (FPC) antenna, 1559 to 1609 MHz, above 4 dBi, IPEX, 40 by 14 mm | No | Match on band; mismatch in form (flat flexible form) and connector | |
RFDPA870900SBGB801 |
Dipole (N, SMA), 1.575 GHz, 0.44 dBi, reverse SMA, 108 mm long | No | Match on centre frequency, no range stated; mismatch in gain and connector gender | |
RFDPA131000SBUB802 |
Dipole (N, SMA), 433 MHz, above 1 dBi, reverse SMA | No | Mismatch: a different band | |
RFANT3216120A1T |
Chip antenna (BT, Wifi band), 2.4 to 2.5 GHz, 2 dBi, 3.2 by 1.6 by 1.2 mm | No | Mismatch: a different band |
A match in the table is a match on the export fields, no more. Confirm against the datasheet and qualify in your own circuit, and note that the greater-than sign in a gain cell states a minimum, so 0.44 dBi and above 2.5 dBi cannot be ranked as written. Our post on choosing a 2.4 GHz chip antenna covers the family the last row comes from, and Walsin RF baluns, filters, couplers and multiplexers covers the neighbouring RF export.
How consistently does the antenna export write frequency and gain?
Not consistently. We counted the Working Frequency Range column: 44 rows hold 22 different strings, and the 2.4 GHz band alone is written 9 ways across 25 rows, including “2.4~2.5 GHz”, “2.4 ~ 2.5 GHz”, “2.4 GHz” and two entries that differ only in internal spaces.
The Peak Gain column mixes a plain value (“2 dBi”, 11 rows), a minimum (“> 3 dBi”) and per-band text (“850 MHz: > 2 dBi 1900/2100 MHz: > 3 dBi”), and 8 rows are blank. A filter on “2.4 GHz” in a spreadsheet will miss most of the 25 rows. We have not seen this counted anywhere. Search by number range, not by string, or paste the part into the cross-reference tool and read the band field.
Which other bands do Walsin antennas list for farm telemetry?
Six rows list a band below 1 GHz. Besides the 3 GNSS rows, our count finds 433 MHz (1 row), 700 plus or minus 50 MHz (1), 840 to 868 MHz (1), 863 to 928 MHz (1), 880 to 960 MHz (1) and 850, 1900 and 2100 MHz (1), against 25 rows in the 2.4 GHz family.
We list bands, not uses. Which band a given radio link may use in Argentina is a regulatory question for your compliance team, and we say nothing about it. The rest of the export is a 13.56 MHz NFC antenna, a WPC antenna stated at 100 kHz and 6 cable and connector rows stated as direct current to 6 GHz.
What does the Hong Kong shelf hold in antennas?
None. Of the 44 antenna export rows, 0 are on our stock list as at 23 September 2026; the list holds 1,125 part numbers across MLCC, chip resistor, safety capacitor, inductor, resistor array and one other line, with no antenna line.
The ready stock list is a dated snapshot, never live-synced, and the antenna range lists the families. If your brief needs an antenna, ask for a to-order enquiry through the site; we will say plainly what we hold and what we do not.
What will we not tell you about farm electronics?
Anything about your receiver, your antenna placement or your radio approvals. We hold 0 datasheets for the antenna line among the 28 Walsin datasheets (26 MLCC, 2 chip resistor), so every figure here is read from the export, not from a datasheet, and the gain and band cells need checking on Walsin’s own site.
We make no claim that any antenna suits a seeder, a sprayer or a drone, or that a band is permitted for a given use. We hold no ISO 9001 or IATF 16949 certificate. We hold no office, entity or stock in Argentina; our locations are Hong Kong, Shenzhen, Singapore and Jiangmen, with Chengdu in preparation. We give no legal, customs or conformity advice; confirm with your compliance team. Qualification stays with you.
How can Venatech help an Argentine agri-tech maker?
How Venatech helps starts with a free paste box. The cross-reference tool (VenaMatch) decodes 18 manufacturers’ part numbers, covers 800,000+ crossable parts, accepts up to 500 part numbers or an Excel or CSV file, and shows Walsin candidates with each field marked match or mismatch. Load a whole BOM for a check. The ready-stock list is a Hong Kong snapshot dated 23 September 2026.
Worked example from our own export: the 1575 MHz receive-antenna brief returned 3 rows in 3 notations, none stocked, so the practical answer is a short list and a datasheet check, not a lookup by string. Walsin is the only line we are authorised for; Stackpole and Viking are lines we supply. We serve from Hong Kong in small lots, we help cross-reference, and you request a quote through the site.
The short version
For an Argentine agri-tech maker, a GNSS antenna is a small list: 3 of 44 Walsin export rows, written as a range, a wider range and a single frequency, with gain cells that cannot be ranked and none on the shelf. Search by number, then read the datasheet.
Send us one antenna line from your BOM, with the band, connector and size you can accept, and we will return the Walsin candidates with every difference stated. If your incumbent prints only “GPS”, do you know which band and which connector you are buying?

Frequently asked questions
What did Infobae report about ERCA at Expoagro 2026?
On 16 March 2026 a company feature said ERCA presented Fertisystem, a variable and controlled fertiliser dosing system for its Linea 7 seeder platform, and an alliance to distribute the EAVISION J-150 drone nationwide. These are the company’s claims, not ours.
Which Walsin antennas cover the GNSS band around 1575 MHz?
Three export rows: RFDPA141300SMGB701 (1565 to 1606 MHz, SMA), RFFPA401410IMGB301 (1559 to 1609 MHz, IPEX) and RFDPA870900SBGB801 (1.575 GHz, reverse SMA). They differ in form, connector and stated gain. None is on our shelf.
Can I compare the gain of the three Walsin GNSS-band antennas?
Not as written. One cell says above 2.5 dBi, one above 4 dBi and one 0.44 dBi, and a greater-than sign states a minimum. Check each against the Walsin datasheet and test in your own assembly.
Why does a spreadsheet filter miss Walsin 2.4 GHz antennas?
The export writes the 2.4 GHz band in 9 different ways across 25 rows, including spacing variants. Filter by a number range or search for the digits 2.4, then confirm each row.
Are Walsin antennas on the Hong Kong shelf?
No. None of the 44 antenna export rows is on our stock list as at 23 September 2026. The snapshot is dated, not live, so ask for a to-order enquiry through the site.
Which radio bands are allowed in Argentina?
We do not say. That is a regulatory question for your compliance team. We list only the bands stated in the Walsin export.
Do you hold stock or an office in Argentina?
No. We hold no office, entity or stock in Argentina; our locations are Hong Kong, Shenzhen, Singapore and Jiangmen. We hold no ISO 9001 or IATF 16949 certificate and give no legal, customs or conformity advice.
