Mobile Antennas

The IPT-2425M is an omni directional mobile antenna intended for 2.4 GHz Wi-Fi use. It measures 4 cm/1.5″ OD x 11 cm/4.5″ H and is designed to conveniently mount onto any structure, by means of a single 1/4″ hole, 5/8“ hole with N connector, or magnetic mount. Its internal radiating structure is self-contained and operates well with or without a ground plane. Therefore, it can be mounted on a non-conductive support, as needed by your application. Also this antenna is foam filled for maximum vibration and moisture prevention for severe environments. This antenna can be produced with most custom mounting options, and many connector options as well.

Coming soon to the rail market is our new locomotive i-TRAC System. A fully integrated antenna rail/trough system that will cover the entire PTC range of frequencies, as well as other optional bands. With the capability of having 14 single antennas, or using dual or tri-band as well in the mix, all your communications needs will be covered. Filtered or unfiltered antenna versions available, as well as custom designed isolation parameters to meet your needs. With our easy placement/replacement antenna system, one can change out an antenna in under 2 minutes without the hassle of removing an entire radome. Fully field replaceable antennas will save valuable downtime, and easy access should you need to change bands, frequencies, or add more antennas to the network. With our dual rail/trough system, space diversity modes can be easily implemented. Our blind mate connector system assures fast reliable connections to your communications equipment.

 

With the i-TRAC System, one can mount our system exactly the same way each time insuring stable reliable rf coverage each time. Optimal placement in the middle of the loco roof is not always available, that means changes in ground planes, and varying conditions to the antennas’ performance overall. With the i-TRAC Antenna System, performance is more predictable each time a system is installed. Each antenna has its own radome that is matched to the frequency it is intended for. That means peak performance from each antenna every time. Also with our system, we have nothing performing under 0 dBi or unity gain. Even our 220 MHz antenna performs at up to 3 dBi of gain. Unheard of for the rail market until now. True vertical performance, and plenty of bandwidth for those less than perfect conditions. All of the antennas are dc shunted for maximum protection to the radio. The i-TRAC Antenna System is easy to install, made of 6061-T6 aluminum, and easy to add on to for future additions of antennas should the need arise.

 

Bi-directional or omni only antennas available for the HEOT or 220 MHz bands available. With bi-directional, one can increase performance up to several times in gain compared to omni mode antennas.

 

Our low profile, rugged mounting system, without the need for welding, will insure years of dependability. Our unique sealing system will guarantee the best watertight seal in the industry.

 

Picture Coming Soon

Our VHF locomotive antenna is a twin to the 220 MHz version using the same style of radome, base and antenna design. With up to 2.0 dBi of gain, and true vertical/omni polarization, this antenna will perform superior to other types of antennas using an inverted F design which are of unity gain. 4 MHz of bandwidth will more than cover the required bandwidth needed in the rail industry. This antenna also supplies more gain than any antenna currently used in the rail industry.

We incorporate a DC shunt design as well to this antenna for extra protection to the radio.

This antenna’s base mount can be customized to fit any bolt hole design such as the typical “ice skate” design found on locomotives today. Incorporating an HEOT antenna on the same mounting base will allow two antennas to work on a single base so one can utilize a single entry hole in the loco roof. By removing the old “ice skate” type antenna, we can utilize the same bolt pattern saving valuable roof space. One can even add a bi-directional style HEOT antenna so gains of 7 dBi can be achieved forward/aft of the locomotive.

The IPT-LM-200-3-NF is a heavy duty wide banded mobile antenna engineered for severe vibration environments. A Xenoy foam filled radome prevents unwanted moisture, condensation and vibration that can short live antennas in less than friendly environments.

The easy screw on base and permanent base mount makes installation much simpler and we back up sealing with a 3-way redundant sealing system. Our blind mate connector system makes changing out the antenna simple if ever need be, as coax inside of the cab does not need to be removed. Our blind mate connectors simply mate on the external side of the base and mounting base eliminating the need for dropping a head liner to remove in coax from the inside. If you want to switch from 200 MHz to 150, 160, or other VHF frequencies, just unscrew the radome, and install one of our other identical made radomes to change frequencies. We utilize the same radome and plates for matching up different bands without the hassle of completely removing the roof base plate.

Performance is unequaled with the IPT-LM-200-3-NF antenna. True vertical polarity, 3 dBi of gain, and the widest banded antenna available with 19 MHz bandwidth is guaranteed to cover the entire 200 MHz band. DC shunted for extra protection to the radio’s receiver as well. VSWR is also the lowest in the industry with less than 2.0:1 VSWR across the entire 19 MHz of bandwidth.

Available in multiple custom base applications, we can supply retrofits for installing on most any surface with any bolt pattern one wishes to apply.

IPT was the first antenna manufacturer to engineer and design a ruggedized end of train antenna system. This series of antennas have proven themselves with over 10 years of service and 1k’s of units in the field. Antennas are easily adaptable to all late model EOTs including those with turbine generators. All units incorporate field replaceable antenna coil for fast simple replacement without the need for going to repair shop should antenna fail while in service.

This mobile antenna is sure to be a hit covering almost any frequency range in the UHF band utilizing a single antenna. Other styles of antennas can require 5-7 different models to cover the same bandwidth as compared to the PMUA-4252. The antenna is also DC shunted to protect the radio receiver from static discharge and unwanted noise. With our broadband design one can expect performance close to higher gain models that have a much narrower bandwidth resulting in higher vswr and lower output power levels once the antenna is operated outside its limited bandwidth range. The PMUA-4252 antenna has a very “hot” or “active” design incorporated into it. It will not detune easily like other antennas. No capacitors or other components ever to fail either. This antenna will actually do up to 185 MHz of bandwidth depending on ground plane size under a 2.0:1 vswr. Compare that to the competition!

We have had customers buy the PMUA-4252 replacing 5 dBi mobile antennas because of better, more uniform coverage of repeater towers. With multiple repeaters or channels operating on wider bands of frequencies than narrow band antennas can operate in, the PMUA-4253 will perform like a pro.

Power: 100 watts
Mount: NMO or ¾” style mount, N-female for permanent type mount, other             custom mounts per request

Our bi-directional antenna is a unique style of antenna. By incorporating a figure 8 pattern, up to 7 dBi of gain can be increased in the forward/aft position to the train. By adding more gain in the direction of the train we can achieve more reliable communications to the EOT unit. N-female, UHF female type connectors, or pigtail w/connector available.

 

If an omni antenna is all that is required, we also offer an omni version with up to 3 dBi of gain in a true omni pattern. Custom bases can be easily adapted to fit existing “ice skate” designs so one does not have to drill new holes in the locomotive roof. Typical base configurations are permanent N female, 4 bolt hole pattern to fit existing “ice skate” base, or our eot design base with extended 5/8” stud mounting system using any type of connector or pigtail configuration.
