Eightwood Dual Band WiFi Antenna 2.4GHz 5GHz RP-SMA WiFi Antennae

Bottom line: The Eightwood Dual Band WiFi Antenna 2.4GHz 5GHz RP-SMA WiFi Antennae ($15.80 on Amazon as of 2026-10-06): 6.5ft extension cable moves antennas out from behind a metal case; main trade-off: RP-SMA only, so SMA-connector cards need a separate adapter.

Pros & Cons

Pros

  • ✓ 6.5ft extension cable moves antennas out from behind a metal case
  • ✓ Magnetic base clamps to steel desks, shelves, or cabinet sides
  • ✓ Dual band 2.4GHz + 5.8GHz with 802.11ax/WiFi 6 support
  • ✓ RP-SMA fits PCIe cards, motherboard WiFi, routers, USB adapters

Cons

  • ✗ RP-SMA only, so SMA-connector cards need a separate adapter
  • ✗ Omnidirectional pattern spreads gain instead of focusing it
  • ✗ Magnet needs a steel surface; no adhesive or screw mount included
  • ✗ Two stubs require manual angle tweaking to find the best signal

Manufacturer description

The Eightwood dual band WiFi antenna set solves the problem most desktop builders hit after installing a PCIe wireless card: the stock stub antenna sits behind the case, pressed against a metal panel and a tangle of cables. This kit gives you two RP-SMA omnidirectional antennas on a 6.5ft extension cable with a magnetic base, so you can lift the antennas onto your desk, a shelf, or the side of a steel cabinet and point them where the signal actually is. Both antennas cover the 2.4GHz and 5.8GHz bands and support 802.11 b/g/n/ac/ax, which means they work with WiFi 6 network cards as well as…

SpecPicks Verdict

SpecPicks scored Eightwood Dual Band WiFi Antenna 2.4GHz 5GHz RP-SMA WiFi Antennae using a rating × review-volume × price-fit model applied to published specs and reviews across the networking category. Eightwood's networking lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here. Judge it on the specification table and the price rather than on sentiment: check the figures that decide your use case, then put it side-by-side with two or three close alternatives in the Compare tool before clicking through.

Common buyer scenarios for networking of this kind: matching it to an existing build, replacing a failing part, or upgrading from a previous-generation equivalent. Check the spec table below against your current setup — particularly socket / form-factor / power-rating fields — and confirm compatibility on the retailer's listing before purchase.

Frequently Asked Questions

Will these antennas work with my WiFi 6 PCIe card?

Yes. The antennas support 802.11 b/g/n/ac/ax, so WiFi 6 (ax) cards are covered, along with older b/g/n/ac hardware. Confirm your card uses RP-SMA connectors, which is the standard on desktop PCIe WiFi cards.

How long is the extension cable?

Each antenna comes on a 6.5ft extension cable. That is usually enough to route from a PCIe card at the back of a tower up onto a desk surface or a nearby shelf for better line of sight to the router.

Do I get one antenna or two?

The kit includes a dual antenna set, which matches the two RP-SMA connectors found on most desktop PCIe and motherboard WiFi cards. Both are omnidirectional and cover 2.4GHz and 5.8GHz.

Will this improve my Bluetooth range too?

On combo WiFi and Bluetooth cards, Bluetooth shares the 2.4GHz band with WiFi, so repositioning the antennas can improve coverage and reception stability for headsets, headphones, and wireless controllers connected to that card.

How do I mount the antenna base?

The base uses a strong magnet, so it holds vertically on a steel surface such as a case panel, filing cabinet, or shelf bracket. Eightwood recommends trying several locations and adjusting the two stubs to different angles to find the strongest signal.
