Rosewill RNX-AD7D 7dBi High-Gain Dual-Band Network Directional Antenna

Your Best Choice of Dual Band Antenna

Complaints about the poor signal of your Wi-Fi from a 802.11AC router? Why not try the Real High Gain Dual Band Network Antenna Stand of Rosewill. According to the research, the Wi-Fi range of 802.11AC is only half of 802.11n.

It means when you upgrade your wireless router to 802.11AC, the distance of your indoor Wi-Fi coverage is no longer the same as you were used to before. To help customers use the Wi-Fi conveniently, Rosewill launches a series of Real Dual Band Network Antenna products. Unlike the low cost and counterfeit dual band antennas, we test our network antennas rigorously to create ubiquitous indoor Wi-Fi environments for users. Still feeling annoyed with your Wi-Fi range? Give the network antennas from Rosewill a try.

Applied Routers Included, but not Limited To:

  • ASUS: RT-AC68U, RT-N66U RT-AC66U
  • NETGEAR: R7000,
  • D-Link: DIR-655 DIR-665

4 out of 5 eggsVery nice results

Pros: Compact, light weight, good positioning ability, satisfied with performance improvement

Cons: For a directional antenna, not to have a label (or some marking) indicating either Front or Back is a major oversight.

Other Thoughts: First things first - the Front of this antenna is the side that has all dimples and NO smooth rectangular box. The Rear of the antenna is the side with a smooth rectangular box, where you might put something like a logo or a label that says REAR.

I work in the commercial radio industry and after comparing the dbm losses of both sides with a spectrum analyzer, the Front became apparent. In my home environment I measured a -10dbm to -12dbm difference between sides. Remember, the smaller the overall negative number, the better the performance. Negative numbers are losses. Positive numbers are gains.

You can use an Android app called WiFi Analyzer to measure the -XXdbm number in the 2.4G and 5G bands around your house. If the stock antennas give you a -40dbm reading and then you swap in the Rosewill antenna (1 or 2) and now the reading is -30dbm, you have increased your signal strength in that area where you point the Rosewill antenna. EVERY environment is different. If person A gets -20dbm improvement and you only get -10dbm improvement, that does NOT mean your antenna is bad. Your environment and/or positioning is different.

Repositioning your router (even by a foot, sometimes) can make a surprising difference. Signal scatter (bouncing off other objects) can impact performance both positive and negatively. Have patience and play with antenna positioning. Take measurements.

Remember, don't have all the antennas vertical - too close a proximity will have negative effects - the interaction will cause the reduction of signal and transfer performance.

My router (Nighthawk R7000) is now using 2 RNX-AD7D antennas - one on the left and right. Stock antenna in the middle. Location of router is basement of 2 story house. Late 1930s era. Plaster walls and metal lathe in them. The metal lathe is what holds the plaster up. It is also a terrible barrier for most RF signals. Forget any reliable cellular service in the house. The router is on a stand angled up at a 75 degree angle. My center antenna is vertical. My left antenna is angled back and faces 45 degrees left. My right antenna is angled back and faces 45 degrees to the right. The FRONT of the RNXs are facing the areas that where I want to provide more signal strength. Always have the front of the antennas facing away from each other!

This setup has resulted in measurably improved signal strength on the second floor (where I needed it). So, the purchase was a good one.

Remember, your mileage WILL vary and each environment is different, requiring different solutions.

My 4 egg rating should NOT be construed as a knock against the product. I only give 5 eggs for truly stellar products.

2 out of 5 eggsStock antenna works better

Pros: It wasn't DOA I guess.

Cons: No signal strength improvement over a stock antenna whatsoever. Bulky and heavy. I put my stock antenna back on. Nice dust collector. BTW it was used with Rosewill wireless adapter, which sucks as much as this antenna.
