Optimized UHF Band Reception (470-862 MHz)
Designed specifically for UHF channels, covering most digital TV broadcast bands, providing more stable signal reception and more comprehensive channel searching.
7-8 dBi Gain & Low VSWR (≤1.5)
Provides medium-to-high gain, effectively enhancing signal reception capabilities, reducing signal reflection loss, and resulting in clearer and smoother pictures.
3-meter Coaxial Cable + IEC Interface
Longer cable for more flexible installation; standard IEC interface, compatible with most TV equipment, plug and play.
ABS Housing & Wide Temperature Range (-40℃~85℃)
Rugged and durable, waterproof and rustproof, adaptable to extreme temperatures, suitable for both indoor and outdoor installation, with a longer service life.
No Power Required, Green and Energy-Saving
Purely passive receiver design, consumes no power, does not generate heat, environmentally friendly and energy-saving, stable operation 24 hours a day.
Application Scenarios
Urban Apartments: Placed on a windowsill or next to a TV cabinet to receive local UHF high-definition channels, replacing cable TV.
Suburban Residences: Installed on rooftops or balconies, it captures signals over long distances, solving problems of weak signals and limited channels.
Dormitory or Rental Housing: Lightweight and portable, easy to install temporarily, suitable for students or short-term residents.
Shops or Public Places: Used for displaying televisions and receiving surveillance signals; economical and practical.
Outdoor Camping or RV Travel: Portable and easy to use with a portable TV, allowing you to watch news and entertainment anytime.
FAQ
Q: Can this antenna receive VHF channels?
A: No. The GL403 is optimized for the UHF band (470-862 MHz). For VHF channel reception, a full-band antenna is recommended.
Q: Does it include a mounting bracket?
A: No. The antenna itself is a separate device. For outdoor mounting, a universal mounting bracket can be purchased separately.
Q: Can it be used with older TVs?
A: Yes, as long as the TV has an IEC interface (the common coaxial interface). If it has an older RF interface, an adapter is required.
Q: Is it safe to use in the rain?
A: Yes, the ABS material is waterproof and can be used outdoors in rainy weather, but prolonged immersion or extreme weather conditions are not recommended.
Q: How do I adjust the antenna direction?
A: This product is vertically polarized and vertical installation is recommended. When the signal is weak, you can slightly adjust the angle and use the TV signal detection function to assist in positioning.
Q: Does it support 4K Ultra HD channels?
A: Yes. As long as the local broadcast 4K channel is within the UHF band, it can be received and played.
