2017年12月30日 · If the radio doesn't have a connection for an external wire, an external, tunable loop (like Fifties mentioned) will help. Just place it near the radio and tune the antenna as you tune the radio. Even a small 1 ft. loop will add 1-3 db to your signal levels, depending on the radio, and depending on conditions.

2020年4月2日 · And a bit of capacitance. It electrically extends the antenna length bringing it closer to Broadcast band resonance. You should be able to add a variable capacitor in series to improve tuning and reception. A 30 ft antenna with a xistor radio ferrite antenna coil and variable capacitor in series works good in most locations.

2019年1月17日 · Further, the physical connection to the radio of such an antenna is unclear to me: < My Zenith H725 has an internal loop AM antenna, and does not have any available external method of attaching an AM antenna. How do I accomplish the attachment? < Do I have to attach both the antenna wire & a ground wire to the radio? Thanks,

2018年1月18日 · Yes, the AES antenna coil will need a short antenna, except for the strongest stations. You don't want to use an external earth ground because the insulation is clearly not heavy enough. The antenna can be coupled through …

2014年11月3日 · Overkill for casual shortwave listening, but #14 AWG steel antenna wire with a thick outer copper cladding (not a plating) is the premium wire for ham radio antennas. Will survive a hurricane if properly installed, but installation is not easy because the steel wire is …

2005年6月6日 · Hello I have two old tube radio aged 1950/60 one with capacitor variable, the second with the inductor variable.<BR>The antenna is just a single wire connected to the rear.<BR>Both cover 500-1620 KHz and 6Mhz-23Mhz<BR>I connected the radio to a single outside horizontal random wire of about 15 metres (as Windom 1923 scheme, 36% off-centre fed) and it works great even if it is less then 1/4 wave.

2025年1月16日 · Hi all. I am in need of the Antenna Coils for an Admiral 11s, particularly the one circled in red, the one ...

From 1924 to 1932 Emerson Radio and Phonograph Corporation distributed radio receivers bearing the name Emerson through many diverse channels, including department and sporting goods stores. In 1932, Emerson began to specialize in small receiver sets for home use. One of these sets was the now very collectible and desirable model 25.

2019年11月9日 · Larry, Thanks for your suggestion. I turned the radio on with out the antenna connected, I had the link between G an A2. When I touched a grounded wire to the G terminal and drew a small arc and got the same 60 cy. hum. I'm sure the is AC on the antenna circuit, now I know what to look for. Jeff
