- 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
- 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
- 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
- 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
- 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
- What are the best uses for 800 900mhz? - RadioReference. com Forums
So put another way, on the cruise ship the "range" of my DLR1020 1 watt FHSS 900 MHz radio was "16 decks" while the "range" of my 4 watt and 5 watt VHF and UHF analog and DMR radios was just a few decks So "range" totally depends on your application, and is not always best measured in miles anyway

Unication G2 in the UHF C band (400-470MHz) for sale with the desktop charging dock This unit will monitor analog frequencies and also connect to any APCO P25 Digital Trunking systems that have Phase 1 (FDMA) or Phase 2 (TDMA) talkgroups
- 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:
