GME LE504 15 Metre RG213/U Coaxial Cable Pre-Terminated PL259 and N Type Connector Low-Loss Extended Antenna Cable Run The GME LE504 is a 15m RG213/U coaxial cable pre-terminated with a PL259 connector at one end and an N Type connector at the other. It is the extended-length sibling of the LE503 (10m), suited to antenna installations requiring a longer cable run between the antenna and radio where minimising signal attenuation over distance is important. Ready to install with no soldering required. Product overview RG213/U is a 50-ohm coaxial cable with a larger diameter and lower signal attenuation per metre than the more common RG58. Over a 15-metre run, this lower attenuation characteristic keeps signal loss manageable where a run of RG58 the same length would lose significantly more signal. This makes the LE504 appropriate for mast-mounted marine VHF antenna installations, commercial antenna systems, base station setups, and any installation where the cable run between the antenna and radio exceeds what the 10-metre LE503 can cover. The PL259 connector at one end suits SO239 antenna sockets found on the majority of marine VHF radios, UHF CB radios, and base station equipment. The N Type connector at the other end suits professional and commercial equipment with N Type inputs, offering a robust, weatherproof threaded connection suited to outdoor and exposed installation locations. Both ends are factory-terminated and ready to install. Features and benefits 15m RG213/U coaxial cable - extended low-loss run: Low signal attenuation per metre compared to RG58, keeping signal loss manageable over 15 metres. Suited to extended antenna-to-radio cable runs. PL259 connector suits SO239 antenna sockets: Standard large-body coaxial connector compatible with SO239 sockets on marine VHF radios, UHF CB radios, and base station equipment. N Type connector - robust and weatherproof: Threaded, weatherproof coaxial connector for professional and commercial equipment with N Type inputs and outdoor or exposed installations. Pre-terminated both ends no soldering required: Factory-terminated and ready to install directly out of the packaging. 15m length - extended run option: Suited to mast-mounted antenna installations, base station setups, and installations where the 10m LE503 is insufficient. Technical specs Specification Detail SKU LE504 Brand GME Type Coaxial Cable Assembly Cable Length 15 metres Cable Type RG213/U Connector 1 PL259 Connector 2 N Type Frequently asked questions How does the LE504 differ from the LE503? The LE504 is the 15-metre version of the LE503 (10 metres). Both use RG213/U cable with a PL259 at one end and an N Type at the other. Select the LE504 when the cable run between the antenna and radio exceeds 10 metres, or when the additional length provides greater installation flexibility. Why use RG213/U cable rather than RG58? RG213/U has a larger diameter and lower signal attenuation per metre than RG58. Over a 15-metre run, this difference is meaningful RG58 would lose significantly more signal across the same distance. For mast-mounted marine antennas, commercial systems, and extended cable runs where signal quality matters, RG213/U is the appropriate cable choice. What is the N Type connector? The N Type connector is a large, robust, weatherproof threaded coaxial connector used in professional and commercial radio and antenna installations. The threaded coupling provides a secure, moisture-resistant connection suited to outdoor and exposed locations. It is not directly compatible with SO239 sockets and requires an N Type input on the connected equipment. What applications is the LE504 best suited to? The LE504 suits mast-mounted marine VHF antenna runs, fixed base station antenna installations, commercial vehicle antenna systems, and any installation where the cable run exceeds 10 metres and low signal loss is a priority. What connector does my marine VHF radio use? Most marine VHF radios use an SO239 antenna socket, which accepts the PL259 end of the LE504. The N Type end connects to equipment with an N Type input such as certain antennas, splitters, or commercial radio equipment. Confirm the connector types on your specific equipment before purchasing.
