External antennas for MURS radios.

In this second video in my MURS radios for RV series, I look into using external antennas. While this is probably not necessary for your average weekend camping trip, if you are involved in rallies, camping groups, or similar events, a MURS radio with an extended range can be very helpful. The theoretical maximum distance was calculated factoring in the free space attenuation at 150Mhz, radio transmit power, receive sensitivity @ 20dB Signal/Noise, base station gain, and mobile antenna gain. The maximum assumes an unobstructed line-of-sight, such as aircraft-to-aircraft, and no atmospheric or environmental interference. A 1/4 wavelength antenna at 153mhz (approximate center of the MURS frequency band) is 18.3" You can watch the first video from this link:    • Use MURS radios on your next camping trip.   Items used in this video include: -------------- Advertisement --------------------- Firestick MURSBase Antenna: https://amzn.to/3nDWePo RG8X Coax - 50 Ohm (40ft): https://amzn.to/3tMjXOo SMA-M to PL259-F Adapter: https://amzn.to/3hJ4vxF Antenna Adapter Plate: https://amzn.to/3zfOmpf Mobile Antenna: any jelly bean magnet-mount antenna covering 153Mhz will work.
