商品描述

TECSUN AN-48x 是一款主动环天线,用于增强短波 (SW)、中波 (MW/AM) 和长波 (LW) 接收。

AN-48x 配有适配器,可将天线连接到 BNC 和 RCA 插座。这极大地简化了将天线连接到接收器,如 Tecsun S-2000 和 S-8800,同时它也与 Tecsun PL-880 和其他 "PL" 系列一起使用。

AN-48x 还适用于没有外部天线插孔的便携式收音机。

Great little antenna.

I've been using this with a HackRF to listen to hams out there chewing the rag and pounding away on CW. Honestly, for an inexpensive, super compact receive antenna, it works amazingly well. Due to the small size of the dials on the tuner/amplifier, it can be a bit fiddly tuning in the antenna, but once you do the difference is really quite amazing. I use it inside my bedroom hanging from a lamp right next to a whole mess of electronics around my computer and the receive quality is excellent. It really works well around the 80 meter band. In fact, it works far better than a number of much larger shortwave antennas I've used on it. I haven't done much on a regular SDR with it yet, but I have to believe it would work quite well for that as well. It really is a good buy for someone extremely limited on space who wants to tune into the ham bands, or any shortwave bands really. Due to it's incredibly small packed size, I also bet it would be fantastic for out and about usage as well. It is quite directional, but with the included hook and clip, it's easy enough to turn in any direction to catch a hard to nab signal. Gets a solid recommendation as far as I am concerned.

I got it because I live in an apartment and I wanted to improve my reception...the kit filled the need.

Easy to set up, just follow the instructions. Finding the stations works well. Needs a battery !

The ease of setting the antenna up and finding frequencies. For an exterior antenna, it’s pretty good.

Works well

The antenna works quite well depending on placement...It's not terribly effective if it is mounted on a wall inside an apartment.
It amplifies RF noise if used this way

It works better if it is placed in a window that faces outside in an area not obstructed by buildings, etc

It worked best when I mounted it on a wall on my patio, with the connecting wires running through a gap in the door when it is left open an inch or two...this improved AM and Longwave the most (I usually only receive a few longwave beacons...with the antenna I can receive a few Longwave broadcast stations from the UK, Ireland and North Africa...the audio is faint, but I can hear it...the first time I have actually been able to hear longwave stations in all my 45 years listening to sw and lw bands...
