Watson-Miller Shortwave Listener (SW) Receiving Antenna (WMSWA) has a Listed Price of £ 69.95 GBP which is ~ $ 139.50 USD ~ EURO 88.70 EUR You now state that you already have a : 30 Foot End-Fed Long-Wire (30 Ft. EFLW) Antenna in use. IMHO - That is a better beginning then to try and use a smaller and shorter 6 Foot Long bent Antenna made-up of 12 Foot of Metal. Your Present 30 Foot End-Fed Long-Wire Antenna has a 5-to-1 Advantage in Size over the WMSW Antenna. Meaning the 30 Ft. EFLW Antenna should be better. Your Present 30 Foot End-Fed Long-Wire Antenna has a 2.5-to-1 Advantage in Length over the WMSW Antenna. Meaning the 30 Ft. EFLW Antenna should be better. The 'crude' calculation for Signal Capture Area * 30 Foot End-Fed Long-Wire Antenna 30' x 12" x 1" = 360 Square Inches * WMSW Antenna 2m x 39.37" x 3" = 236 Square Inches Which is 1.5-to-1 Advantage in Signal Capture Area Meaning the 30 Ft. EFLW Antenna should be better. KEEP - The 30 Foot End-Fed Long-Wire Antenna. QUESTIONS : Q # 1 - Vangellis are you using a good earthen 8-Foot Copper Ground Rod with the 30 Foot End-Fed Long-Wire Antenna and for your Radios and Equipment in your Home ? * You Should Be. + Improve your Antenna and Radio Shack with a Ground for Less Noise and Better Safety. Q # 2 - Vangellis are you using a Coax Cable feed-in-line with the 30 Foot End-Fed Long-Wire Antenna ? * You Should Be. + Improve your Antenna with a Coax Cable feed-in-line for Less Noise and a Better Signal.

Q # 3 - Vangellis is your 30 Foot End-Fed Long-Wire Antenna 'configured' in the Shape of an Inverted "L" Antenna ? * It Should Be. + Make Qs 1, 2 and 3 a lot easier To-Do and All Three 'together' work a lot better {Synergy} for Less Noise and a Better Signal.
