Coverage Antennas
Selected by coverage shape and mounting conditions: ceiling antennas for indoor fill, panel antennas for outdoor zoning, Yagi and parabolic for long reach. The antenna is not an accessory — it is the first link in coverage quality.
Indoor coverage antennas
Ceiling antenna
The standard indoor-distribution antenna: wide beam, ceiling mounted, for corridors and room fill.
Indoor directional flat panel
Narrow-beam coverage for long corridors, lift lobbies and other linear spaces.
DAS indoor distribution antenna
Used with an indoor distribution system; configured by zone and branch count.
Outdoor coverage antennas
Panel / directional flat panel
The workhorse of outdoor zoned coverage; gain and horizontal beamwidth chosen by sector.
Omnidirectional antenna
360° coverage for wide-area sites from a tower top or site centre.
Whip antenna (mobile / handheld)
For mobile and handheld radios, with magnetic-mount and fixed-base options.
Private-network base-station antenna
Supplied with the private base station; determined together with site planning and sectorisation.
Directional link antennas
Yagi antenna
High-gain directional, used for donor links and long-reach runs; strongly directional on installation.
Log-periodic antenna
Broadband directional — one antenna covers several bands, suited to unsettled frequency plans.
Parabolic / grid antenna
Point-to-point long links across buildings or terrain, with strong interference rejection.
Radio service antennas
VHF radio antenna
136–174 MHz, for forestry, water conservancy and coastal applications.
UHF radio antenna
400–470 MHz, the main configuration for hotels, hospitals, campuses and factories.
Antenna & feeder assembly
Jumper and feeder cut to site length with terminations fitted; insertion loss measured before dispatch.
- Where fiber can be laid, prefer fiber remote units and let the antenna do the final distribution; use wireless links only where cabling is impractical.
- Isolation between the donor and service antennas decides system stability — isolation must exceed the system gain by 10–15 dB.
- Vertically separated mounting usually gives better isolation than horizontal; floor slabs, parapets and lift shafts are useful natural shielding.
- Every antenna is measured for VSWR and gain before dispatch, with test records supplied; interfaces and bands follow the contract configuration list.

Send the floor plan and coverage requirement; we will issue antenna placement, feeder routing and a link insertion-loss budget. On-site survey can be arranged where needed.
