For this antenna, which cites a VSWR of 1.4, can that be improved (decreased) with the use of a matching network? Could the matching network be between the feed cable and the board or must it be between the antenna and the feed cable?

    \$\begingroup\$ On the AM band, for a receiver ... you're over-thinking it. Just connect it. It's not like you'll have 30kW of power reflected back into a transmitter. Not a reliably measurable signal loss, no. \$\endgroup\$ – user_1818839 May 16 '18 at 21:30

    \$\begingroup\$ With all due respect: If antenna design questions are considered "off-topic" in an ELECTRICAL ENGINEERING forum, I daresay that James Clerk Maxwell would be very disappointed in you. Amazing \$\endgroup\$ – Seamus May 16 '18 at 21:50

    \$\begingroup\$ In an effort to shed some light on your question, I would say this, "Yes, it can be improved with a matching network, but at a 1.4 VSWR, it hardly seems worth the effort, and your EIRP could be lower even with a lower/better VSWR." \$\endgroup\$ – Seamus May 16 '18 at 21:54

    \$\begingroup\$ Hmm. This seems like a legit question, which would lead to better understanding of RF fundamentals. Vote to reopen, anyone? \$\endgroup\$ – bitsmack May 16 '18 at 22:22

    \$\begingroup\$ @bitsmack I agree it's a perfectly reasonable question (reopened) even though the answer is basically "don't bother". If you're after the last 0.5dB of performance then it's theoretically possible ... but you'd be better starting off with a decent AM loop antenna instead. Perhaps aa7ee.wordpress.com/2013/11/17/… or radiomagonline.com/misc/shielded-loop-antennas-for-the-am-band Much more likely potential for improved performance. \$\endgroup\$ – user_1818839 May 17 '18 at 10:53
