That said, it ultimately will depend on what the specs of the antenna you are using are. If it's something like this:


then as you can see the smallest beamwidth is 40 degrees so that would allow for you to be 20 degrees off centre either way.





That's the one. In fact, I have two of them though I am having other problems right now. I was getting constant 50 Mbps down on speed tests for some months. At the beginning of the year this suddenly dropped to 18 Mbps max, usually less, sometimes as little as just 2 or 3. We can't figure out why but our streaming has become unusable. The antenna's don't appear to have shifted, but that is the reason I asked my question. Now I am wondering if the Huawei could possibly be faulty. The speed has recovered briefly once or twice, but then it dropped back down again. 





I seem to be in the exact predicament as well.
Same Aerial, same modem, same problem, different ISP.

ISP is Farmside, who were very unhelpful when it came to advising on the issue. Their solution was to send a tech ($150+gst) to look at the aerial incase it had moved. With the beam angles previously advised, a degree of rotation should not cause a major issue, if it had moved at all. It would have been easier if the tech who did the install, marked its alignment at install time, so I could visually check if it had moved.


Apparently 4G is not available, however the connection when set up was showing 4G at full strength, and down and up connections were around the 30Mbps mark. Now seeing 3G connectivity and connection speeds occasionally below 1Mbps.

Connection is coming off a vodafone tower.

Interesting to see what comes of this.

nzbsgfan: What coax are you using for your run ? RG213 or better ?

Also can you see your EcNo and receive RF level once you log into the modem ?

I work with these modems at work and I'm not sure what you can see without engineering software - but as a rule lower EcNo values are what you should aim for


Doesnt look like I have access to those number, this is what i can see -


RSRQ goes between -9 and -12dB


Rsrp -117/118 dBm


Rssi -89dBm


PCI 364


Upload frequency 730.5MHZ


Band 28


This is without the external antenna plugged in.  Oddly enough, even with the external hooked up these figures barely change at all, only the Rssi is slightly different at -87dBm.


Does this mean my external antenna is sweet next to nothing to help?

Where did your coax come from??

Spark FibreMAX using Mikrotik CCR1009-8G-1S-1S+. UAP, UAP AC Pro, UAP AC Pro Mesh, Apple TV 4, Apple TV 4K, iPad Air 1, iPhone 6s, VodaTV Gen 2. If it doesn't move then it's data cabled.

An increase in RSSI of 3dB indicates twice the signal. You are currently indicating 2dB increase with the antenna connected.. It is important to note RSSI (receive signal strength indication) indicates the total received signal including the ambient noise.

I'll cut and paste some info below;

RSRP (Reference Signal Receive Power) is the average power of Resource Elements (RE) that carry cell specific Reference Signals (RS) over the entire bandwidth, so RSRP is only measured in the symbols carrying RS. While RSSI (Received Signal Strength Indicator) is a parameter which provides information about total received wide-band power (measure in all symbols) including all interference and thermal noise.

So it would be safe to write that, in LTE, RSRP provides information about signal strength and RSSI helps in determining interference and noise information. This is the reason, RSRQ (Reference Signal Receive Quality) measurement and calculation is based on both RSRP and RSSI.

Cut ends

It's important to reduce your transmission losses - especially in long runs. As a rule of thumb larger diameter coax has less loss per meter. The number of elements on your yagi indicates gain - the more elements the higher the gain and the more directive your antenna. What is the "thickness" of your coax - or alternately post a picture of your coax where it has a connector fitted.

I have a Vodafone yagi and their cable.
I have used a few different cables.and theirs is twice as thick as other low loss ones I have used.
I have an rssi.of 57
