The wires formed one plane of a corner reflector, the other plane was formed by the sloping terrain. <br/>The centreline of the antenna was directed at the north celestial pole, so the antenna received radiation from the same area as the earth rotated . <br/>It wasn&#39;t used for any military or HF communication applications.<br/>So you were right on that. 2025-12-08T23:58:20Z https://nostr.now/nevent1qqsd95q8tylfq7vc2f85je6lsfx57zfwdtcg2lkdtuzfkhvm0xs0c3gzyzkglm69cvzaqwsrfeegl09e265zp8uczs8a09mfudgryjemakk95r0l75e In reply to <a href='/nevent1qqsqf649mkh7xcjr7lhssxlwee503lsxy3rtdfusz0rw0vp2avyfjfgdv05vc'>nevent1q…05vc</a><br/>_________________________<br/><br/>Thank you for sharing your wonderful Psion memories.
