When to Use the RSRF Grid Parabolic Antenna
There are two situations in which we recommend using the RSRF Grid Parabolic Antenna:
1 - If the signal from the cell tower is very weak (i.e. low RSRP)
The Grid Parabolic Antenna has very high gain, which means you can receive an improvement of between 5 dB to 10 dB in signal
strength compared to a log periodic antenna.
2 - If the signal from the cell tower is low quality (i.e. low SINR)
Since the Grid Parabolic Antenna has such high directivity, it can be used to improve the signal quality by focusing on one tower,
reducing the interference from other nearby towers.
If possible, use a lower gain antenna with a
larger spread to find the location and direction
with the best RSRP and SINR.
If you do not have a lower gain antenna
available, scan with the grid 2° - 4° at a time to
find the tower, then fine tune it even further.

(Default as per spec sheet)
POSITION 4 1700-6500 MHz (+1-2dB)

POSITION 2 (+2dB)
POSITION 1 (+1dB)600-750 MHz
750-980 MHz

We cannot state this enough: this antenna has a very, very narrow
beam. The grid can only “see” within a very narrow horizontal and
vertical aperture. Even a 1°- 2° variance can make a huge dierence.
You’ll need to move slowly to find just the right direction.
Once you’ve found it, secure the grid firmly so it’s not blown in a
dierent direction.

Feedhorn Depth Selection
You can select from 4 dierent positions when mounting the Feedhorn. If you’re focusing on one specific band, then choosing a
dierent feedhorn location can help achieve an extra few decibels of gain on that band, while reducing gain on the other frequency
bands.
Pro Tips
▶Getting line of sight to the tower helps immensely
▶If optimizing for signal strength, try to minimize the cable
length
▶If there is a tree line, try to get above it where possible
▶Make sure to ground the antenna and your mast, in case of
lightning storm
How to Aim the RSRF Grid Parabolic Antenna
The RSRF grid parabolic antenna has a very narrow “beamwidth.” That means it will only work when it’s aimed almost exactly in the
direction of the signal source. Even if you’re oby just a few degrees, signal will be significantly degraded.
If you don’t know exactly where the signal is coming from, we recommend starting with a lower-gain, log periodic antenna first. Try
dierent locations and directions with the log periodic to find the best RSRP and SINR you can. Once you have identified the best
location and direction, switch to the grid parabolic antenna and fine tune to find the very best signal.
