  • What is UHF1, UHF2, UHF3, etc? | RadioReference. com Forums
    I've been looking at some radios that operate in the UHF range and have been seeing multiple bands listed in the specifications It's usually listed similar to this: UHF1: 400-470MHz; UHF2:450-520MHz; UHF3: 350-400MHz; UHF5: 806-941MHz I thought maybe the numbering scheme was just an internal
  • VHF UHF radio and antenna questions - RadioReference. com Forums
    The trick with VHF UHF antennas, and this ties into your original question, is elevation Since VHF UHF signals are primarily line of sight, you need to get the antennas as high as you can above surrounding obstructions Granted, there are trade-offs such as putting an antenna on a tall support might require a long, and lossy, feedline
  • Project - Researching, Designing and Building a UHF Horizontal Wire . . .
    The UHF Horizontal Wire Loop Aerial (UHFHWLA) is a simple yet effective DIY antenna project designed for UHF frequencies, particularly for monitoring UHF CB and other active users in the band This aerial builds on principles learned from ultralight DXing tools like Ferrite Sleeve Loop (FSL) antennas
  • DIY HOMEMADE DUAL BAND VHF UHF (2 Meter 70 Centimeter) TUNEABLE . . .
    Since most of the overall Ham bands were chosen specifically based of the principle of Harmonics, yet not immediately being able to find anything solid regarding a DIY VHF UHF Dual Band Antenna, I internally thought, well this is B S There must be a simple way to make a Fan-Dipole equivalent for VHF UHF
  • Luke AFB ATIS VHF vs. UHF | RadioReference. com Forums
    Thus, if the VHF and UHF transmitters are using the same output power, the VHF signal will travel farther, under normal conditions An example that comes to mind is my CB use in the 1960's Using a 4 watt transmitter and roof mounted antenna, I would easily get 15 miles talking to a similar user set-up

    I am looking at the new FTM-150RASP as maybe my next VHF UHF mobile The features are impressive, but I cannot figure out a couple of things that interest me I downloaded the programming software from Yaesu, but it is very buggy I am interested in the expanded receive Besides using it in
  • UHF tunable notch filter trap to block receiver interference
    - Find a UHF cavity and place a coaxial "T" adapter on only one loop, tuned to the notch frequency Adjust the loop and cavity for best results - Buy on Ebay one of the many channel deletion filters made by Microwave Filter Company, which have 8 adjustable cavities to delete a 6 MHz TV channel Remove one and retune
  • UHF Maritime On-Board Communications Frecuencies
    This is my first post in this forum, and I am going to talk you about the UHF frequencies authorised for Maritime on-board Communications They are regulated by the ITU (ITU-R M 1174-4) and the ETSI (ETSI EN 300 720 V2 1 1) and they are used worldwide in big merchant and cruise vessels The spacements, frequencies and channels are the followings:
  • Connect Multiple Radios To One Antenna? - RadioReference. com Forums
    3 There are amplified splitters that can boost the signal power at each output vs the input, but they tend to have bandwidth limitations that must be considered An amplified splitter designed for UHF and VHF broadcast TV reception will work well for signals in those frequency ranges, but may completely block 800MHz signals
