20-6 Meter Loop antenna (72' wire) + 500/1500/5000 Watt PEP rated 4:1 Current Balun + internal 1:1 Current Balun in one enclosure + 4 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 (4 insulators included)
* Choice of 500, 1.5KW or 5KW PEP rated HYBRID 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-4-1-1500/5000 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).
1.5KW Rated for full 1500 watts PEP and 1000 watts CW/FT8 (ICAS). 1.8Mhz – 61 MHz.
5KW Rated for full 5000 watts PEP and 1500 watts CW/FT8 (ICAS). 1.8Mhz – 61 MHz.
500 watt version is in "BULLET" format, 1.5KW is a 4 x 4 x 2 cube and 5KW is in 4" x 4" x 4" enclosure.
Generator RFI testimonial:
Bob Received your order in a timely fashion. Tried the generator kit on Sunday & it drops the noise from S9 to S5 and took out all the electrical noise. I may want some more toroids from you at some point for other interference problems I have here. Ken VE3KCY

If you use a computer for logging in your portable operations, RFI getting into computers will often lock up your computer and/or radio and a computer RFI suppression kits may be helpful
Make your expedition or portable operation a pleasant and fun outing and remember to take along your RFI kits so you have more time to operate rather then to troubleshoot intermittent or noisy receiver conditions.
Portable Antenna Kits
If you need an effective portable antenna which folds up for transport yet is easy to deploy at your operating site, consider the BULLET series of end fed wire antennas.
