Aerials
We supply a range of aerials to work with Mega_Link and Mega_Link 2 best suited to the requirements of your application.
-
PUG/TNC
This aerial is 340mm long and is an effective omni-directional aerial for use with 458MHz licence-free radios.
It is typically fitted to the top of an enclosure (connected to the telemetry module via a bulkhead extension cable) but since it is weatherproof it can also be used on a mast by using an aerial extension lead.

ENF450/xx: 458MHz End fed dipole
This is a very rugged unity-gain aerial that drops into the top of a 2” pole with the cable coming down the centre.

The cable is terminated in a male TNC plug which is included.
-
FUC3, FUC6, FUC10/xx
This is similar in appearance to the ENF450, but considerably longer.
By focussing the radiation pattern in the horizontal plane the gain is increased by 3, 6 or 10dB

UHF3, UHF4, UHF6, UHF8, UHF12/xx Yagi
This 3, 4, 6, 8 or 12-element Yagi, gives 1, 2, 3, 4 or 5dB gain in one direction at the expense of much lower gain in all other directions. Note that a CO/2 is needed to attach it to a mast

The cable is terminated in a male TNC plug which is included.
* Licence-free regulations define the maximum effective radiated power (ERP) in any given direction. When using an aerial with gain the transmitter power output must be reduced accordingly. The benefit given by the aerial is therefore restricted to only improving the receiver sensitivity.
