Antenna for UHF VHF Links →
2m Antennen Preamplifier Vorverstaerker
With a gas-fet CF300, and switchable gain between 14 and 24 dBD, noise figure better than 0.9dB, continuity damping better than 0.2 dB, transmittable power 750 W PEP to 2 meters with these prinelais
2 Meter & 70 Centimeter Mobile Halo
2 m 70 cm dual band antenna, horizontally polarized antenna, with aluminum rod for the radiant element and also copper tube
2m Band VHF Antenna Pre-Ampilfier
I have an old VHF transceiver a little-bit "deaf"! By adding the following VHF pre-amp as 1st stage, the improving of sensitivity is spectacular
2m. Band VHF Collinear with 2 Dipoles
After the dipoles and coaxial cables placement into the mast, its time for the final tuning
2m. Band VHF Dipole with Gamma match system
Collinear antenna project, wich gives a gain of about 5,1 DBi with 2 dipoles and 8,1 DBi with 4 dipoles Omni directional
