Antenne halo 144MHz
The antenna support serves as a coaxial antenna supply line
Antenne pour le portable 145mhz
Antenna squelette (skeleton) is neither more nor less than a QUAD antenna, except that in our case it is rectangular
Antenne slim jim 144mhz
Given its very average rigidity it will advantageously be suspended from a polyamide cord stretched between two supports a few meters rom the ground, the feeder coaxial RG 58 freely
Half-Wave Flower Pot Antenna
The 2m Half-Wave version of the antenna. To construct the antenna, first select a suitable length of grey 25mm
