Antenna Low Bands 80-160m
On the higher bands, the same antenna is usually used for both TX and RX . The Low Bands are different, in that one good TX antenna is probably adequate. If the TX antenna is relatively inefficient, we can compensate by using more power. But for RX, we require antennae that have the very best signal-to-noise ratio SNR

Antenna GP 3,5 MHz a carico lineare
This vertical antenna for 80 meters at linear load, of 1/2 wave is born from the need to have a good angle of radiation
Antenna HF multibanda deltaloop 6-160 metri
We can choose between loop-magnetic and DELTA LOOP, the latter does not require great skills and particularly high manual skills to build it
Antena para 80/40 metros, bobinada e de alta performance
Antenna for 80/40 meters, traps and high performance

23cm Yagi Antenna building Finished antenna at 1275 MHz SWR under 1:1.5 at resonant frequency
50 MHz preamp Gain 26dB with the BFG135 Preamps for 144 and 430 MHz, for 50 MHz, the BFG135a is a cheap transistor and in my view rather strong. It is not easily damaged by static discharge or RF power. FG connection
