## Summary description

Coaxial antenna Renkforce SKB 488-40 designed for the 40 m amateur radio band. This antenna connects via coaxial feed and is intended for transmitting and receiving on the 7 MHz range. It suits home or portable ham radio use where a compact, single-band solution for improved signal performance on 40 m is required.

## Long description

Coaxial Antenna Renkforce SKB 488-40 for 40 m band is a single-band antenna solution for amateur radio use on the 7 MHz (40 m) frequency. The product includes a 40 m coaxial cable with high shielding and multiple F-connectors, designed to provide stable signal transmission for transmitting and receiving on the 40 m amateur band. The heavy shielding and waterproof F-connectors make the cable suitable for long feed lines and outdoor installations where reduced interference and long-distance runs are required.
Advantages
The high-shielding coaxial cable (100 dB) reduces electromagnetic interference and maintains signal integrity over long distances. Waterproof F-connectors included and one pre-mounted F-connector with rubber sleeve ensure reliable, weather-resistant terminations. The 40 m cable length allows flexible placement of the antenna away from the transceiver, and the design supports both transmission and reception on the 7 MHz amateur band.
Suitable for
Amateur radio operators using the 40 m (7 MHz) band
Home or portable HF stations requiring a single-band 40 m antenna feed
Long cable runs where high shielding and waterproof connectors are needed
Key specifications
Brand: Renkforce
Model: SKB 488-40
Manufacturer part number (MPN): 1399967
EAN: 4016139045436
Cable length: 40 m
Cable type: Coaxial (koax)
Connector A (end): open end
Connector B: F-connector (one pre-mounted with rubber sleeve; three additional F-connectors and one spare rubber sleeve included)
Shielding: 100 dB
How to use
Connect the open end of the coaxial cable to the antenna feedpoint and attach the F-connector end to a compatible adapter or equipment with an F-type input as required. If needed, fit the additional F-connectors provided following the manufacturer’s instructions and ensure rubber sleeves are in place for weatherproofing. Route the 40 m cable to minimize bends and avoid parallel runs with power lines to reduce possible interference. Verify coax continuity and impedance match with appropriate antenna analyzer or SWR meter before transmitting.
Usage recommendations
For best performance on the 40 m amateur band, mount the antenna at a suitable height and keep the coaxial run as direct as possible. Use the waterproofed F-connectors outdoors and inspect connector seals periodically to maintain weather resistance. When installing long runs, use strain relief at attachment points to protect connectors and cable integrity.
