175 FT RG11 Quad Shield Coaxial Cable for Underground Use
Trilogy
Comes Pre-made with Connectors already fitted on the Cable ends for Instant Install out of the Box for Direct Burial Cable TV and some Satellite and Antenna applications. This is really big cable with low RF Signal loss for Cable TV, some Satellite and Antenna applications where the Coaxial Cable RF / IF Signal Feed needs to be Installed Underground for long distances between Equipment and Premise. Low Signal Loss Underground Coaxial that Features a PE (Poly Ethylene) Jacket over Two layers of Bonded Aluminum Foil and (2) layers that total 100% Aluminum Braid, Bonded Foam Dielectric with a Copper Clad Steel Center Conductor. Perfect for HDTV, DTV, DBS, Cable TV, Master Antenna and Satellite Master antenna Applications with 1.0 GHz Bandwidth. Can Also be Utilized as an Underground Signal Feed Transmission line from Towers, Dishes, Antennas and Telephone Poles to Home, Office and Premise.
SuperShield (Quad Shield) - Taking the Tri-Shield construction one step further, this construction adds an additional layer of shielding braid to provide the greatest strength, durability and immunity from network interference. Provides low attenuations for service drop inter-connecting jumper cables.

LIOL Low Intensity Obstruction Lighting for Tower Aviation Marking
Low Intensity Obstruction Lighting are lights used to visually mark obstacles and obstructions. These lights are necessary in providing a clear visual indicator and in preventing collisions in poor visibility conditions or at night.
Applications
- Airport Buildings
- Tower Cranes
- High Buildings
- Bridges
- Smoke Stacks
- Cell Towers
- Broadcast Towers
- Communication Masts
- Weather Masts
- Power Substations
- Transmission Line
- Wind Turbines
POWER
Three different types of power technology are used to power these LED LIOL lights.
- Solar- The power is supplied by a battery. This battery is charged during the day using embedded solar panels. At night and when there is insufficient solar available, the units will switch over to battery power. This all happens automatically.
- Universal AC Line Power- Power must be provided using a power cable that can supply AC current (110–240VAC 50/60Hz). Can also be powered with optional solar and/or battery.
- Universal DC Line Power- Power must be provided using a power cable that can supply DC current (12–48VDC). Can also be powered with optional solar and/or battery.
LED TECHNOLOGY
All the LIOL lighting we carry, uses the latest advancements in LED (Light Emitting Diode) technology as a light source. The major advantage of LED’s over traditional light sources is well established in that they typically have an operational life in excess of 100,000 hours, resulting in substantial savings to maintenance and servicing costs.
