When searching for a repeater site, here are key considerations to keep in mind:
1. Elevation
• Higher elevations offer better line-of-sight, which is crucial for GMRS. Look for sites on hilltops, towers, or high-rise buildings to maximize the range.
2. Accessibility
• Ensure the site is accessible for installation, maintenance, and emergency access. This includes considering road access and any restrictions on equipment or building access. Some building locations may not allow full access.
•Towers often require a fully licensed and insured “Tower Climber” to install an update equipment.
3. Power Supply and Backup
• Reliable power is essential for continuous operation. Look for sites with stable power sources and consider backup options, like solar power or generators, to keep the repeater operational during outages.
4. Tower and Antenna Space
• Confirm if there is room on the tower or building for the GMRS antenna. Verify any mounting restrictions, weight limits, or existing congestion.
5. Legal and Zoning Restrictions
• Ensure compliance with local zoning laws and FCC regulations. Some areas may have restrictions on GMRS repeaters, and you may need permits or approvals.
6. Interference and RF Environment
• Check for potential interference from other RF equipment nearby. High-density areas or sites with multiple communication systems can cause signal degradation.
7. Coverage Area Needs
• Identify the specific coverage area you need and use mapping software to determine if the location will meet those requirements. Ensure the site aligns with the intended user locations.
8. Quality of Equipment
• Investing in high-quality equipment is crucial, especially if you plan to use the repeater for many years. While cheaper equipment may meet immediate needs, it can lead to reliability issues, higher maintenance costs, and frequent replacements. Prioritize durable, reputable equipment to ensure a long-lasting, dependable setup.
•a malfunctioning or nonfunctional repeater is of no use in an emergency.
9. Cost Considerations
• Factor in leasing fees, installation costs, and any maintenance fees. Some sites might offer free or reduced rates for community or non-commercial usage.
10. Security and Weather Protection
• Look for sites with secure enclosures for equipment, and consider environmental protection like lightning arrestors, weatherproofing, and adequate grounding.
11. Site Ownership, Permissions, and Leasing Fees
• Make sure you have explicit permission from the property or tower owner to install and operate the GMRS repeater. Sometimes, site owners require a monthly fee or a lease for the area, which can sometimes be considerable depending on location and demand. Document any agreements in writing to clarify costs, permissions, and responsibilities.
Prioritizing each of these factors helps maximize the efficiency, longevity, and performance of your GMRS repeater system.
