Need Advice on Antenna choice for BR1-ENT

Looking for advice regarding the best choice between the two antenna candidates for the BR1-ENT cellular gateway. The BR1-ENT which will be used near the US/Canadian border on a vehicle with a composite (non metal) body) (One US SIM, one Canadian SIM).

We use Verizon 700 MHz (band 13) on the US side. It appears the 1723 has better specs for this 700-800 MHz band, and has somewhat improved performance overall - but I would greatly appreciate confirmation from those that can read and interpret radiation patterns better than I.

The two potentials are:

  • SureCall CM288
  • Digital Antenna 1273

Radiation patterns for SureCall CM288:

Radiation patterns for Digital Antenna 1273:

A number of additional files, including a project summary with goals and the antenna spec sheets can be found here:


Hi Scott, both antennas look like good candidates so I would say this is would be a personal preference on your side. Thanks.

Hi Tim, thanks much. Any thoughts on the band 13 / 700 MHz region. I’m a novice at reading radiation patterns and dBI. Am I reading it correctly that the 1273 has a ~1.5 dBI advantage in that area. Thanks!

Manufacturers will often state maximum gain vs average gain because it is a higher number. If 700MHz is your primary concern I would reach out to each one as to what the gain is for this specific frequency. Thanks.

We don’t use **any Digital Antenna products, our experience is it’s pretty poor quality and poor performing. Between the two, hands down the CM288.

Not sure what the vehicle is, but if commercial and you can tolerate the size, checkout the Shakespeare 5239. It is a rock solid antenna with excellent construction and great performance:

If you’ll be stationary at times then check this thread out:

thanks to both @Tim-S and @Rexymav.

Data has been obtained on both the SureCall CM288 and the Digital Antenna 1273. At this point and on those specific 2 antennas, the data includes spec sheets, radiation patterns, and frequency response. Data was requested from several other antenna manufacturers, including on the Shakespeare Galaxy 5239. Digital Antenna was by far the quickest to respond and the most forthcoming, followed by SureCall, with Shakespeare’s support email bouncing and direct contact emails being returned by an “out of office” message or silence.

Attached is a combined graph, showing the frequency response of the two antennas with applicable LTE bands denoted. A pdf version can be found here.

With all the talent on this forum, I’m hoping to find real world experience and data on these antennas - Please add what you know!

Momentarily disregarding the much appreciated warning from Rexymav, the DA1273 appears to have improved specs in the bands we will be using.

If you have used either of these, please do comment.

Thanks again!

All very interesting… since the pepwave supports MIMO, would you go with a single antenna, or two?

Hello @FredT,
We sugesst you contact your local Certified Peplink Partner, they can help you with a copy of the Antenna Selection Guide for Peplink Partners, this is a detailed guide and is only available to the Peplink Partners so to ensure that you are helped in working through it to get the most suitable antenna solution to your application.

With MIMO modems (regardless of manufacture or brand) if the modem is designed for MIMO operation, then use suitable MIMO antennas setup and designed for MIMO operation, if you are going to spend the money on a MIMO capable modem, then go the whole stretch with the cabling and antennas too, by only using one antenna or cable, you are loosing more than 50% of the benefit of the MIMO design (its not just two antenna connections, there is a lot more to the way these systems work).

Also, do not (make that never) use Television cabling or Television antennas for your connection with a cellular modem, the connection impedance of the cabling and the antenna designs are not suitable. So called “Digital TV” antennas from our experience are more problematic for cellular system than most realise. The simple reason is both the TV cabling & antenna are designed for one way communication & that is receiving a signal, they are not designed for transmission which is a very different process and design requirement.

Happy to Help,
Marcus :slight_smile:
