Earlier this year I decided to compare some of the V-mount batteries available and see what the differences were. Some of it was rather eye opening, and since then I’ve expanded on the original article and have now created a dedicated page for batteries - listing all their specs, including crucially, their relative capacities versus their size and weight.
Wireless microphones and monitors
11 May 2015
Wireless microphones and in-ear monitors in the UK are generally available at VHF (170 - 210 MHz) and UHF (470 - 790 MHz).
There are three ways in which you can legally use them:
The ranges 173.8 - 175 MHz and 863 - 865 MHz and 2400 - 2483.5 MHz can be used without a Licence subject to the requirements of The Wireless Telegraphy (Exemption) (Amendment) Regulations 2006. These ranges are also used by other low power equipment so can be subject to interference.
When you want to track a slow-moving
subject but other subjects or people appear
in the foreground.
