Frequently Asked Questions
Q: What is the difference between a log periodic antenna and a Yagi antenna for RF testing?
A: A log periodic antenna (like our 0.6–10 GHz Log Periodic Antenna) offers a much wider usable bandwidth than a Yagi, making it ideal for broadband EMC testing and RF spectrum analysis where you need consistent gain across a wide frequency range. A Yagi provides higher gain but only over a narrow band, making it better suited for point-to-point links on a fixed frequency.
Q: Which antenna is best for a Helium miner or LoRaWAN gateway?
A: For Helium mining and LoRaWAN applications operating in the 868–915 MHz band, a high-gain outdoor fiberglass antenna is highly recommended. Our 12dBi 868–915MHz Outdoor LoRa Fiberglass Antenna provides excellent omnidirectional coverage and is weatherproof for permanent outdoor installation, significantly extending your network range and potential mining rewards.
Q: What is an EFHW balun and do I need one for my ham radio antenna?
A: An End-Fed Half-Wave (EFHW) balun is an impedance transformer — typically in a 1:49 or 1:64 ratio — that matches the high impedance of an end-fed wire antenna to your 50-ohm coaxial feedline. If you're operating an end-fed antenna on HF bands, a quality EFHW balun like our 1:64 EFHW Balun 1–30MHz 100W PEP is essential for efficient power transfer, reduced RF interference, and proper antenna performance.
Q: What RF coaxial connectors and adapters do I need for my setup?
A: The most common RF connector types in amateur radio and test equipment are SMA, BNC, UHF (PL-259/SO-239), and N-Type. Having a versatile adapter kit on hand — such as our 14-Pc SMA BNC UHF N-Type RF Coaxial Adapter Connector Kit — ensures you can interconnect virtually any combination of RF devices without needing to re-terminate cables in the field.
Q: Can I use a 4-way antenna switch to share one feedline between multiple radios?
A: Yes! A remote antenna switch like our 4-Way Coax Remote Antenna Switch 500W PEP | 1.8–60MHz lets you connect up to four antennas (or four radios) to a single coaxial line, switching between them with minimal signal loss. This is a popular solution for ham radio operators who run multiple HF antennas but want to avoid long cable runs for each one.
