The ELAD ASA-15 is an antenna splitter designed for use in radio communication systems. It allows multiple radio receivers to share a single antenna without interfering with each other or degrading the quality of the received signals.
If you have more shortwave radios than you have antennas this is the solution for you. This is the proper way to share your antennas with your receivers. With an antenna splitter. Here’s my review-
The ELAD ASA-15 antenna splitter
The ASA-15 is designed to work with antennas that have a coaxial feedline, and it has four output ports that can be connected to up to four separate receivers. The splitter uses a high-quality amplifier to ensure that each output port receives a strong and clean signal, and it also includes built-in filters to prevent interference between the connected receivers.
The ASA-15 is also designed to be very easy to use. It requires no external power supply or configuration, and it can be connected to a single coaxial cable in just a few seconds. This makes it an ideal choice for radio operators who need to quickly set up and tear down their equipment in the field.
The ASA-15 splitter is designed to work with frequencies 5 MHz to 1GHz.
One of the key benefits of the ELAD ASA-15 is its compact and lightweight design. It’s not small enough to fit in a radio operator’s pocket, but it can be easily transported and used in the field. This makes it an ideal choice for portable or mobile radio communication systems, where space and weight are at a premium.

Key Features
1. One Antenna, Multiple Radios
The ASA-15 allows up to four receivers to share a single antenna without significant signal degradation.
Typical setups include:
- SDR + scanner
- Multiple SDR receivers
- Ham transceiver receive-only chains
- Shortwave listening stations
2. Wide Frequency Coverage
The splitter operates from:
5 MHz to 1Ghz
This covers:
- HF shortwave
- Airband
- Marine VHF
- Public safety
- Amateur radio bands
- Many SDR monitoring applications
3. Active Amplified Design
Unlike passive splitters that introduce insertion loss, the ASA-15 includes internal amplification to maintain strong signal levels across all outputs.
Benefits include:
- Lower signal loss
- Better weak-signal reception
- Improved SDR performance
4. Isolation Between Receivers
Built-in filtering and isolation circuitry help prevent:
- Receiver interaction
- Front-end overload
- Local oscillator leakage
- Cross-device interference
This is especially important in multi-SDR monitoring stations.
Typical Applications
Shortwave Listening
Ideal for:
- Tecsun radios
- SDRplay receivers
- Airspy SDRs
- ELAD SDR receivers
Scanner Monitoring
Useful for:
- Aviation monitoring
- Rail scanning
- Public safety monitoring
Ham Radio Receive Systems
Can distribute one receive antenna to:
- SDR panadapter
- Main transceiver
- Auxiliary receivers
Advantages
- Wideband operation
- Active amplification
- Four independent outputs
- Compact size
- Easy installation
- Good for SDR enthusiasts
- Suitable for fixed or portable stations
Potential Limitations
- Primarily designed for receive applications
- Not intended for transmitter RF power handling
- Requires quality coax and grounding practices for best performance
- Premium pricing compared to generic passive splitters
Best Use Cases
The ELAD ASA-15 is best suited for:
- Advanced SDR hobbyists
- Shortwave listeners
- Monitoring stations
- Multi-receiver radio desks
- Enthusiasts with limited antenna space
It is particularly valuable when antenna restrictions make it impractical to install multiple antennas. I’m really glad I bought mine and use it daily.
📡 Want better reception?
Your antenna matters more than your radio.
Overall, the ELAD ASA-15 is a high-quality antenna splitter that offers reliable and efficient signal distribution for radio communication systems. Its compact design, easy-to-use interface, and high-quality signal amplification and filtering make it a popular choice for both portable and fixed radio communication setups.
