My main antenna system for 144 MHz is a 4 x 9 element Xpol DF7KF design. It is a high gain antenna system at all ~18 dB(d) working fine in EME with still good SWR when raining or little ice on it.
My second 144 MHz antenna is a 11 element DK7ZB OWL wide band antenna. This antenna is still working with cm ice on it .

50 MHz is a 6 element PA50-6-6 by antennas-amplifiers.com
