    Ben your link is wrong.

  2. Ben Ellison Ben Ellison says:

    Thanks, John. I fixed the link in the entry, and it’s also here:
    The rare February thunderstorm line that just passed over my area — picture wicked soggy snow and wet sheets of ice — was fairly well predicted by Baron yesterday, with graphics. Impressive.

    Ben, I have been pushing Wave to market a MIMO bridge router for the last 3 years. I’m glad to see they have finally launched this product. I have found using a combination of horizontal and vertical polarized antennas provides the best N MIMO performance.

    I am very interested in connecting an external antenna to my Verizon AirCard (which is connected to my Cradlepoint Router, in hopes of pulling in a stronger signal. I looked the Digital Antenna 1273 and see the 1285 mentioned above.
    Has anyone had suggess using either of these antennas? I -4db gain has me wondering if any gain from the antenna will be lost in the cable and connectors with a negligible benefit?

  5. Bill Lentz says:

    Henry, I have been using something similar but made by CellPhoneMate, the model CM288W. Although it lacks real gain it is a true 698MHz to 2700MHz antenna unlike the compromise antenna inside or on your VZW aircard. My performance is like night and day when using the external antenna. Think about this, how would your aircard work if you could mount it high on your vessel?
    Then ask yourself how would it work with a decent antenna mounted high on your vessel?
    These antennas help even though they are low gain.

  6. Ben Ellison Ben Ellison says:

    Thanks, Bill. The CM288W may be the same thing as the Shakespeare Galaxy 5239 mentioned in my entry:
    Did you use LMR400 or similar for cable?

  7. HenryD says:

    Bill and Ben,
    I have my Cradlepoint router and Verizon Aircard in the pilothouse approximately 15′ off the water. I can put an external antenna on the mast or pilothouse roof and gain another 5-10′. I am hoping just the design of the antenna helps some over what is probably 1-2″ of wire in the Aircard.
    The Digital Antenna, Shakespeare and CellPhoneMate all seem to be similarly sized, shaped and specs.
    Any difference that you noted?

  8. Ben Ellison Ben Ellison says:

    Henry, Digital told me that their 1200 series wideband bullet antennas were designed specifically for marine use by founder Dr. John Jones and also that they’re made in the USA.

  9. Bill Lentz says:

    I mounted mine on a spreader above my Radar dome about 20′ feet above the boats waterline. I used LMR400 cable. I had great results I am using a Samsung UML290 USB modem into a CradlePoint CBR350 router. I actually installed 2 external antennas one for the 2G/3G/4G (MIMO port) and the other antenna and feedline for the dedicated 4G LTE 700MHz only port on the Samsung VZW modem. In my installation the router used to sit inside a fiberglass hull inside an equipment cabinet. Even when I removed the modem/ router to a shelf near a window my results were 10 to 15db worse as a stand alone modem/ router. What I’m trying to say is the antennas built into my VZW LTE/ CDMA modem are compromise antennas and could be blocked depending on where I stood. With the now 2 year old setup it really rocks. The best way to measure performance on a cellular device is by getting into the devices trace mode. CradlePoint makes this easy because the RSSI or RSRP (for LTE) can be directly measured so it’s a data based test and signal improvements are easy to measure. I also use a small USB extension to get the Samsung VZW USB modem away from the CradlePoint routers radio this also improves performance.
    I hope this helps.
    I did install a VZW specific 700MHz LTE amplifier and a 2G/3G direct connect amplifier. I found them to actually make my speeds slower. They are still installed and with a few jumper changes I can put them back on-line if needed but I haven’t had the need in over a year.
    I’m no fan of a specific BDA manufacture but I did install one of their Sprint 3G amplified cradles to another CellPhoneMate external antenna and it cleaned up my fluctuating EcIo and vastly improved my RSSI on CDMA.
    For high speed data I think it’s hard to beat VZW they are so far ahead in site builds and 700MHz propagates extremely well. AT&T would be my second choice for high speed data.
    I have an Ericsson W35 still installed but deactivated that used to work great on HSPA+ it is connected to a Digital 563W. I’m looking to get rid of the W35 in the near future.

    I’m currently working on a project that will use 2 of these antennas inside a KVH M3 dummy dome. The dome will house an upgraded CradlePoint router as well as the Samsung USB modem. It will be replacing my Skipper 150 and balancing the looks on my arch because the port side has a working M3 TracVision system.
    It should be a good looking performing cellular based data/ VOIP package.
    In my last post I didn’t mention that I have been successfully using an inexpensive VOIP system over VZW’s LTE network with excellent results. The VOIP box feeds a DECT cordless phone system which supports Bluetooth so that position allows me to make and receive calls from my Samsung Galaxy smartphone using on Sprint’s service.

    Do check out while you can. I learned this morning that it’s just a quickly thrown together demo that will go offline in a few weeks. The idea is to show off some of the marine weather products that Baron wants to supply to apps and web site developers, and even MFD manufacturers. Apparently some partnerships will be announced soon.
    I’m particularly impressed with what’s called “future radar” or the “5km BAMS” weather model (they’re the same). I’ve seen some uncanny specific precipitation forecasts presented in the same way we see realtime NEXRAD. Also impressive is the ocean currents forecasting which includes weather, not just historical data and recent measurements. And there’s much more.

    I have two antennas I am going to try.
    I just recieved a TerraWave M3060070O10006OSS – cellular phone / Wi-Fi antenna from Tessco. And am in conversation with Wilson Electronics for the correct adapter from my UML295 to the “N” connector on the antenna.
    Thanks – Henry

  14. Bill Lentz says:

    Henry, please post the results of your new installation. I have a UML290 so I’m not sure if my USB modem uses the same adapter/ jumpers as the newer UML295. The 3G Store is a good source for adapter cables for various modems.

    The new little weather widget on the top of Panbo’s main page doesn’t look like much but it links to some really interesting widgets that I put on my About page today. You can even set them to remember the U.S. site you’d like to keep track of:

  16. Bill Lentz says:

    Henry did you install the antennas to your VZW LTE modem? Did the upgrade increase performance?

    Inmarsat Fleet One satellite communications for smaller boats has purportedly gone live:
    The tiny terminal with “data connectivity up to 100 Kbps, a single voice line and SMS” plus Inmarsat’s 505 safety service sounds interesting. But I can’t find anything about hardware or service pricing. Anyone?

  19. Alan Spicer says:

    I keep up on this stuff including what’s actually inside the routers making it work … always in search of the newest level of WiFi or nG where n is currently 4G LTE. The problem with the newest level of 4G LTE is #1 hardware being available, particularly routers, and #2 the cellular carriers actually supporting it. There is some new stuff out that can switch US / CAN cellular carriers with just a firmware update, and routers that can do multiple plug in modem modules – so US and US (2) or US and EURO/ASIAN (2) is possible. The external antenna connection on these routers is much nicer SMA than anything on a USB stick would have – if they have anything at all. A newer embedded card module will actually have the carrier switching firmware files already onboard it – which will cause heck for mfr.’s trying to charge support fees for getting something that should be FREE. I’m glad to see some boats actually installing 2 antennas for the MIMO support of both WiFi and 4G / 3G systems as this is really a necessity although most don’t want to run the cables and mount the antenna to do it.

    I had the pleasure of being one of the BETA testers for the Wave WiFi N MIMO unit. It uses the same graphic user interface the original units used and it can be tailored for Smart Phone mode with one click. I use it with a single cross polarized Omni sold by Ubiquiti under the AirMax antenna line.
    I have always recommended that people use dual antennas even prior to 4G. Many 3G systems can benefit by using diversity reception. There are modems that support this mode. For the best N MIMO and 4G results you should use cross polarization antennas.
