FAQ
TL;DR: Mount two ATK‑10s cross‑polarised on the same mast; a 50 cm vertical offset is “no difference.” Aim both at the same BTS. [Elektroda, matek451, post #16894007]
Why it matters:** This setup boosts LTE‑800 stability and speed on Huawei B315 without guesswork—ideal for rural links.
Quick Facts
- Orientation: one horizontal, one vertical; aim both at the same BTS. You can swap B315 cables if needed. [Elektroda, matek451, post #16893953]
- Spacing: 50–60 cm between antennas works; a 50 cm height difference is negligible. [Elektroda, matek451, post #16894007]
- LTE‑800 throughput: theoretical max ~75 Mb/s down on Orange-class networks. [Elektroda, makosuu, post #16902301]
- Real‑world peak seen in thread: ~70 Mb/s after tuning; one higher spike was a one‑off. [Elektroda, mysiul, post #16904013]
- Example cabling: Tri‑Lan 240, 10 m runs reported working well. [Elektroda, mysiul, post #16894863]
What’s the best way to mount two ATK‑10s on a metal tube for LTE‑800?
Mount one antenna horizontally and the other vertically on the same mast. Point both at the same BTS. If performance seems off, swap the two SMA leads on the Huawei B315 and retest. “Antennas towards the same BTS.” [Elektroda, matek451, post #16893953]
Should the horizontal antenna be above the vertical one?
Either order is fine. A 50 cm difference in height between the two antennas does not change results in this scenario, so place them as the mount allows. [Elektroda, matek451, post #16894007]
What spacing should I keep between the two antennas?
Keep roughly 50–60 cm separation along the mast. The thread confirms that even a 50 cm vertical offset is negligible, so that distance is a practical target for rooftop installs. [Elektroda, matek451, post #16894007]
How do I connect the two antennas to a Huawei B315?
Connect each antenna to a separate external antenna port on the B315. If initial readings are worse than expected, swap the left/right cables and re‑aim with live RSRP/RSRQ/SINR feedback. [Elektroda, matek451, post #16893953]
How do I align and verify the antennas using signal metrics?
After mounting both antennas, slowly pan toward the target BTS while watching RSRP, RSRQ, and SINR. In the thread, no‑antenna RSRP was −100 dBm; alignment and dual antennas delivered strong speed gains. Lock settings where SINR peaks and RSRQ rises. [Elektroda, mysiul, post #16894277]
What download speeds are realistic on LTE‑800 with B315?
Expect up to about 75 Mb/s down on LTE‑800, depending on network load and radio conditions. This aligns with the LTE‑800 cap cited in the thread and matches typical rural performance when the site is uncongested. [Elektroda, makosuu, post #16902301]
Why did I see one speed test above the LTE‑800 limit?
The thread shows a single unusually high result, followed by repeated tests topping out around 70 Mb/s. Treat rare spikes as anomalies or transient radio conditions; sustained results reflect the true link rate. [Elektroda, mysiul, post #16904013]
Is one ATK‑20 better than two ATK‑10s?
Two ATK‑10s are easier to mount and less visually intrusive. An ATK‑20 is about 170 cm long and needs sturdier hardware. If aesthetics and mounting are fine, some users would choose two ATK‑20s; otherwise, dual ATK‑10s are a solid pick. [Elektroda, mysiul, post #16894554]
What coax cable length and type worked for the poster?
A 10 m run of Tri‑Lan 240 coax was reported working well with the dual‑antenna setup. Keep runs as short as practical to reduce loss, and weather‑seal connectors. [Elektroda, mysiul, post #16894863]
What does “BTS” mean in this context?
BTS refers to the cellular base station you’re targeting. Both antennas should face the same BTS to maximise signal quality and MIMO benefits in the B315. [Elektroda, matek451, post #16893953]
How do I set this up? (3‑step quick start)
- Mount two ATK‑10s on the mast, one horizontal and one vertical, facing the same BTS.
- Connect each to a separate B315 antenna port; if readings are odd, swap ports.
- Fine‑tune aim while monitoring RSRP/RSRQ/SINR, then secure mounts. [Elektroda, matek451, post #16893953]
Does a 50 cm height difference between the antennas hurt performance?
No. The contributor states that a 50 cm difference makes no practical difference for this setup, so focus on correct orientation and aiming. [Elektroda, matek451, post #16894007]
Can I use a wall‑mount tube as the bracket?
Yes. You can arrange a suitable wall bracket yourself or purchase one. Ensure it’s sturdy enough for wind load and antenna length. [Elektroda, makosuu, post #17265974]
Which thread metrics show improvement after adding antennas?
Before antennas, metrics included RSRP −100 dBm and SINR 13 dB. After installing two ATK‑10s and aligning, throughput jumped dramatically, confirming better link quality. Track RSRQ and SINR during fine‑tuning. [Elektroda, mysiul, post #16894277]

I plan to buy an LTE 800 antenna, a Huawei B315 router and need advice, is it more profitable to buy one ATK-20 dipole antenna? Is it better to add a little and buy 2 ATK10 antennas? and mount them the way you did it
