Hi I'm hoping that someone can help. I have been interested in amateur radio since my school's days in the amateur radio club and have also always loved sailing. I now find myself trying to combine the two interests and making a receive only setup for my boat focusing on the MF and HF bands. I however am really struggling to select an antenna or set of antennas with a selector switch that will provide the best possible reception for use on a 26ft sailing boat. I would be really grateful to hear any advice you have regards to antennas and related equipment to point me in the right direction. Further details are below. Many thanks James Boat: Contests 26 sailing boat with a single 28ft aluminium mast and wire rigging. Hull made of Fiberglass and an inboard diesel engine. Boat radio: Software defined radio SDR play RSP1a connected to a raspberry pi 4 using the software cubicSDR and Fldigi Frequencys required using one or two separate antennas: Navtex on : 490khz 517khz Weather fax on : 3855 kHz, 7880 kHz, 13882.5 kHz and 2618.5 kHz, 4610 kHz, 8040 kHz, 11086.5 kHz 18261kHz Marine communication and safety information: 2172kHz, 4125kHz, 6215kHz, 8176kHz, 8291kHz, 12290kHz, 12359kHz 16420kHz, 16537kHz Other installed equipment: Icon marine VHF set with marine VHF antenna mounted at the top of the mast. Budget: trying to keep the cost down as much as possible but don't mind spending money if it really makes a difference. Thanks again.
