RFI COL7 UHF Collinear Antenna, 380-530 MHz
3dBd lightweight collinear with minimal wind loading for broad-bandwidth single frequency or duplex applications.
Overview
The COL7 is a lightweight collinear design with minimal wind loading, making it ideal for mounting on moderate support structures. The radiating elements are constructed from alodined aluminium and are arranged as a series fed array. The internal elements are enclosed in a fibreglass radome which is fitted to an aluminium mounting tube.
These are 3dBd gain omnidirectional collinear antennas characterised by broad operating bandwidths, making them suitable for single frequency or duplex applications. The antenna is internally DC grounded for lightning protection and dissipation of static noise.
Key Features
- 3dBd (5dBi) gain means solid omnidirectional coverage across the broad 380-530MHz band.
- Lightweight design with minimal wind loading means it's ideal for mounting on moderate support structures.
- Broad operating bandwidth means suitability for single frequency or duplex applications.
- DC grounded design means better lightning protection and reduced static noise.
Applications
- Single frequency or duplex UHF base station applications
- Sites requiring low wind and tower loading
- Moderate support structures where a lightweight antenna is preferred
- General purpose UHF coverage in the 380-530MHz band

FAQs
Why choose the COL7 over a higher-power collinear?
The COL7's lightweight design and minimal wind loading make it ideal for moderate support structures where reducing tower loading is a priority, while still delivering solid 3dBd gain across a broad UHF bandwidth.
Is this antenna suitable for duplex applications?
Yes, the broad operating bandwidth of the COL7 makes it suitable for both single frequency and duplex applications.
