RollingRob has shared notes from BVARC Meeting - Receive Antennas with Rick W5RH, Feb 12 . Meeting covered club announcements and Rick W5RH’s presentation on receive antennas. Announcements: life membership badges will be personally handed out; HamFest Feb 20–21; Summer Field Day Jun 27–28; Woodlands Marathon/Half Marathon Jun 28; Museum Ships Weekend Jun 5–7 (Pelican Island/Galveston Naval Museum). Monday night net grew to 16 attendees; President logo in emails increased response. HamFest needs volunteers (raffle ticket sales); special guests: a Medal of Honor recipient and an Artemis talk. Emergency drill with Red Cross set for end of March (third week), 2-meter band, K-Plan; volunteers needed. Rick’s presentation focused on improving SNR via receive-only antennas: small loops, phased verticals, Beverage-like ground systems, and diversity. Key metric: Seeding Directivity Factor (RDF), e.g., 7.4 dB to 9.6 dB. Modeling with EasyNEC showed pattern improvements. Small loops reduce local noise but are low-output and need preamps.
