80-10 Meter Loop Antenna System with 4:1 Balun and Choke Combo, 3-30 MHz, 500/1500/5000 PEP OptionProduct DetailsMPN: PAL-8010LOOP-500, -1500, -5000Country/Region of Manufacture: USAInput ohms/Output ohms: 50 in/200 outFrequency Range < 2:1 SWR (MHz): Balun rated at 1.8-61 MHz for 1.5KW, 1.8-31 MHz for 3KW/5KWPEP Power Rating (watts): 500W/1.5KW/5KWInput Connector: SO-239Output Connector(s): Eyebolts/Wing NutHardware Type: Stainless SteelEnclosure Size: 4"x4"x 2"(1.5KW), 4"x 4" x 4"(1.5KW/5KW)80-10 Meter Loop antenna (288' wire) + 500/1500/5000 Watt PEP rated 4:1 Current Balun + internal 1:1 Current Balun in one enclosure + 6 insulators for support
* Complete package - just add coax
* works multiple bands with ease
* can be configured as delta, square, rectangle or multi-sided horizontal loop (6 insulators included)
* Choice of 500, 1.5K, or 5KW PEP rated baluns to suit power needs
* No need for extra feed line choke as it is built into the 4:1 balun enclosure
After many requests we have created a compact, special balun for OCF and loop (Skyloop or Delta loop) antennas. The CB-4-1500OCF is a CUBE enclosure containing a multi-core, broadband 4:1 impedance transformer in series with a 1:1 current balun for extra common mode current choking to keep RF current off the outside of the coax braid and on the antenna where it belongs. The extra choking action also means that the coax feed line will not act as a radiator causing unnecessary RF interference (RFI).
1500 watt is in 4" x 4" x 2" enclosure and 5KW is in 4" x 4" x 4" enclosure.
ADD MC-1-3000 Choke for radio end of coax to reduce common mode noise on coax up to 6 "S" units!

Christmas lights or yard lights with switching DC power supplies are often the RFI source and a clamp on ferrite bead on the AC AND the DC side feeding the lights is needed to help suppress the switching power supply RFI noise. Suitable snap on beads are FSB31-1/2 for the 1-250 MHz range.
We have also had reported wireless HDTV boxes, and FOSCAM and AMCREST security camera systems causing RFI to garage door remote openers. Use our Garage Door Opener RFI kit to suppress the interference to the opener (VICTIM) – you need one kit for each opener. Maximize the distance from the camera to the openers may also help. Additionally shield cable to the garage door sensors may be needed depending on severity of the camera RFI.
Obvious Tech Note: make sure your remote batteries have enough energy to activate the GDO or the signal they transmit may not be large enough to over ride the RFI signal, but a fresh battery may be able to overcome the weak RFI source and allow the GDO to operate correctly.
