Systems Engineering Request

Please answer the questions that apply to your project—this questionnaire is general. If there are specific details you'd like to share beyond what's covered here, we're happy to discuss them during the design phase.

To help us better understand your requirements, we welcome any supporting materials such as site photos, equipment drawings, schematics, or descriptions of your existing setup.

For international customers, we use U.S. Customary Units of measurement. If your specifications are in Metric units, please clearly indicate this in your drawings or documents.

If your project involves high-power transmitters with nearby antennas (e.g., TV/FM broadcast, paging, NOAA weather), please include their frequency and power levels.

Also, let us know the frequencies of any nearby receivers relative to your transmit antennas.

System Antenna/s

Antenna selection and configuration can be very complex and are specific to each installation location and desired coverage area/s. Telewave.io Systems Engineers can discuss options & trade-offs for each case.

Antenna/s duplexed? (TX & RX share Ant) or separate TX & RX Ant? (Supplied or Not)(Required)

Duplexed (TX & RX share Ant)

Separate (TX & RX Ant)

How much distance will there be between antennas?(Required)

For Separate TX & RX antenna, will they be Horizontally or Vertically separated?(Required)

Vertically

Horizontal

Both

For Separate TX & RX antenna, what is the max Horiz/Vert separation avail? (ft/meter)(Required)

Do you need antennas?(Required)

Yes

No, I already have antennas

Describe any specific Antenns requirement, pattern, gain, tilt, or mounting desired.(Required)

System Component Mounting (Panels/Rails – 19 inch Rack/Cabinet)

Cavities for frequencies below 108 MHz are very long and heavy. They can only be mounted using rails. The rail assemblies can then be mounted vertically inside a rack/cabinet or attached to a wall/ceiling.

Cavities for frequencies above 108 MHz can be rack-mounted vertically on rails or horizontally on panels.

Some VHF/UHF cavities for frequencies between 108 MHz to 512 MHz require 30 inches from the face to the bottom of the cavity and an additional 6 inches from the face to the end of fully extended tuning rods. Note these max installed dimensions when planning for horizontal or vertical installations in racks/cabs.

The 48-inch-tall by 24-inch-wide racks for 10-inch cavity combiners are obsolete and no longer available.

System mounting - Panels or Rails? (See notes above)(Required)

Panels

Rails

How tall (RU)?(Required)

If you need an open Telco rack, how tall? Our standard heights are 72 or 84 inches.(Required)

If you need an enclosed cabinet, how tall? Standard height is 72 inches – Color Black(Required)

For an enclosed cabinet do you need door locks?(Required)

Yes

For the door locks, do you need a key or combination?(Required)

Key

For an enclosed cabinet do you need wheel/castors?(Required)

Yes

With or Without Locks?(Required)

With Locks

Without Locks

System Frequencies

Please provide the requested information below. You may either complete the table or submit the information in a separate document. Be sure to indicate the name or intended use of each frequency, including those designated for optional use or future expansion. For Public Safety and all Trunked Systems, a transmitter duty cycle of 100% is assumed.
