RF Filtered DC Power Adapter — TV Antenna & Amplifier
Last updated: April 2026
Sunshine, a longstanding manufacturer, specializes in the production of RF filtered DC power adapters for TV antenna amplifiers, signal boosters, and distribution equipment. With two dedicated power adapter facilities situated in China and Vietnam, we offer competitive bulk pricing for the SQ1014/SQ1015 series — desktop switching power supplies with built-in RF filtering and F-connector output, engineered specifically for the TV antenna and signal distribution market where standard unfiltered adapters introduce noise into the RF signal path.
Key specifications of our product include:
Variants: SQ1014 15V 1.2A (18W) | SQ1015 12V 0.6A (7.2W)
Input: 100–240VAC, 50/60Hz universal
Output connector: F-type coaxial (matches antenna amplifier RF input)
RF filtering: Built-in low-pass filter prevents switching-frequency noise from entering the RF signal path
Surge protection: 1KV / 4KV / 6KV optional
Energy class: DoE Level V / VI optional
Regional plugs: US, EU, UK, AU
Globally certified: UL 62368-1, FCC Part 15, CE, RoHS, REACH
With over two decades of power adapter manufacturing experience, Sunshine is a reliable supplier of RF filtered adapters to TV antenna brands, signal distribution equipment manufacturers, and consumer electronics distributors across North America.

Why Choose Sunshine’s RF Filtered Power Adapter
Sunshine’s SQ1014/SQ1015 include a built-in RF low-pass filter between the switching power supply circuit and the F-connector output — a filter stage that standard desktop power adapters do not have. Without this filter, the switching-mode converter’s high-frequency harmonics (typically 50–500kHz) travel down the F-connector cable and enter the antenna amplifier’s RF signal path, manifesting as horizontal noise bars, herringbone patterns, or general “snow” on the TV picture. The RF filter attenuates these harmonics by >40dB before they reach the amplifier, keeping the DC output clean enough for direct injection into an RF signal chain.
This is not a theoretical concern — it is the number-one field failure mode reported by antenna amplifier OEMs whose customers substitute generic unfiltered power adapters for the RF-filtered original. The replacement adapter “works” (correct voltage, correct current) but degrades TV picture quality in ways the customer attributes to the amplifier rather than the power supply. Sunshine’s SQ1014/SQ1015 eliminate this problem at the supply level.
Applications
The SQ1014 (15V 1.2A) and SQ1015 (12V 0.6A) are specified for TV antenna preamplifiers (mast-mounted and attic-mounted), TV signal distribution amplifiers (multi-output splitters with active gain), antenna rotator power supplies, and OTA (over-the-air) signal boosters for cord-cutting TV setups. The F-connector output plugs directly into the amplifier’s power-passing input port — no adapter or barrel-jack conversion needed.
The SQ1014 at 15V/1.2A is sized for multi-output distribution amplifiers and high-gain preamplifiers. The SQ1015 at 12V/0.6A is sized for single-output preamplifiers and compact signal boosters. Both ship with interchangeable regional plug options (US, EU, UK, AU) for multinational antenna equipment brands shipping the same amplifier SKU to multiple markets.
Customization and OEM Services
Output voltage (5V–15V), output current, surge protection level, energy efficiency class, housing color, printed branding, and retail packaging are customizable. For antenna amplifier OEMs bundling the power adapter inside the product box, we provide custom packaging with your brand’s UPC barcode and quick-start guide insert. MOQ is 1,000 units per variant for stock and 3,000 units for custom.
Certifications and Compliance
Every SQ1014/SQ1015 lot is tested to UL 62368-1 for safety, FCC Part 15 Subpart B Class B for electromagnetic emissions, CE and the EU Low Voltage Directive for European market access, and RoHS plus REACH for environmental compliance. The RF filtering is verified by spectrum analyzer measurement confirming >40dB attenuation of switching harmonics at the F-connector output.
How to Order
Contact our sales team with your target variant (SQ1014 15V or SQ1015 12V), regional plug types, quantity, and destination market. We return a quote within 8 hours across US and EU time zones.

Frequently Asked Questions
Why can’t I use a regular power adapter with my TV antenna amplifier?
You can — it will power the amplifier. But a standard switching power adapter generates high-frequency harmonics that travel through the F-connector into the amplifier’s RF signal path, causing picture noise (horizontal bars, herringbone patterns). An RF filtered adapter like the SQ1014/SQ1015 attenuates these harmonics by >40dB, keeping the RF signal clean.
What is the difference between SQ1014 and SQ1015?
SQ1014 outputs 15V at 1.2A (18W) — sized for multi-output distribution amplifiers and high-gain preamplifiers. SQ1015 outputs 12V at 0.6A (7.2W) — sized for single-output preamplifiers and compact boosters. Both have the same RF filtering and F-connector output.
What MOQ and lead time should I expect?
MOQ is 1,000 units per variant for stock and 3,000 for custom. Lead time is 25–35 days. Multi-variant orders (SQ1014 + SQ1015 on one PO) ship on the same production timeline.
