The TT820-3600 cellular whip antenna is an external rod-style antenna for compatible wireless terminals. Its listed frequency ranges cover several cellular bands, including 3400–3600 MHz. The vertical-polarization and omnidirectional pattern specification makes it an option to evaluate for gateways and equipment requiring surrounding coverage.

Use the detailed band list
The electrical table specifies 820–960, 1710–2130, 2320–2655 and 3400–3600 MHz. Those separate ranges are more precise than the model name. Check all modem bands against the table instead of treating 820–3600 MHz as continuous validated coverage.
Plan the antenna orientation
The listed polarization is vertical. Mount and test the antenna in the intended equipment orientation and assess nearby metal or other conductors. An omnidirectional description generally refers to a pattern plane; it is not a guarantee of equal reception in every direction.
Check the radio connection
The interface is listed as SMA-J. Confirm the exact mating connection and polarity from the drawing before procurement. For a multi-port modem, provide the corresponding number of RF antenna paths and evaluate their spacing and interaction.
Validate gateway performance
The electrical specification lists VSWR no greater than 2.0:1 and efficiency of at least 65%. Review the measurement setup and compare installed performance. Enclosure placement, cable loss and network conditions remain relevant to the final data connection.
Frequently asked questions
Does TT820-3600 support every frequency between 820 and 3600 MHz?
Use the separate operating ranges in the specification. The model name is not a continuous-coverage guarantee.
Can a higher-gain antenna guarantee a faster connection?
The result depends on installed radiation performance, modem capability and the network. Compare the complete terminal.
