Inverted L End Fed Antenna System with Coax Interface including 1:1 feed line choke - 160/80M and 1.5KW/5KW PEP optionsProduct DetailsMPN: PAL-INVL80-1500/5000 or PAL-INVL160-1500/5000Country/Region of Manufacture: USAInput Connector: SO-239Output Connector(s): Eyebolts/Wing NutHardware Type: Stainless SteelEnclosure Size: 4"x4"x 2"(1.5KW), 6"x 6" x 4"(5KW)Inverted L antenna with radiator and counterpoise for simple installation - choose 80/160 meters and 1.5KW/5KW feed line choke included inside weatherproof enclosure. Separate counterpoise and ground connections
* Complete package - just add coax
* works single band with ease
* can be configured as vertical or inverted L configuration
* Choice of 1.5K, or 5KW PEP rated choke to suit power needs
After many requests we have created a compact, special interface box with internal feed line choke and separate connections for counterpoises (not grounded) and ground connection. The 1:1 choke keeps 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).
80 M radiator/counterpoise is 70 Feet (you get 1 each) - adjust length to your favorite frequency
160 M radiator/counterpoise is 130 Feet (you get 1 each) - adjust length to your favorite frequency
Antenna is tuned to you favorite frequency by shortening the counterpoise (roll it up or cur length) while keeping the radiator length constant.
Choose 1,5KW PEP or 5KW PEP options.
1.5KW and 5KW are in 4" x 4" x 2" enclosure. 1.5KW is 3 pounds, 5KW is 5 pounds. 2 antenna insulators are included.
ADD CMNF-1500 (1.5KW) or CMNF-5000 (5KW) common mode noise filter at radio end of coax to reduce common mode noise up to 6 "S" units on long coax runs!

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.
