Review Summary For : NI4L Portable End-fed 40-6m Dipole
Reviews: 1MSRP: $58.98
Description:
This is a 40 foot insulated wire with an insulator at one end and the other end fed through a 9:1 transformer with a tap that may be grounded. The transformer is housed in a box with an SO-239 for the feed line and two screw terminals with wing nuts, one for the ground and the other for the wire. Use of the ground is optional. The box is approximately 3.5x2x1 inches not including connectors and had two mounting tabs for attaching it to a surface with screws (not provided). The entire antenna including the rolled-up wire can be carried in a gallon zip-loc bag with room the spare.

Surprisingly effective under the circumstances Time Owned: 0 to 3 months.
I wanted an antenna I could install indoors and not have to disconnect during stormy weather. I have a different end fed mounted externally on the house that works acceptably but it requires a large coaxial balun that won't fit inside. The NI4L had mixed reviews but its small size and simple configuration made it worth trying.

It fits perfectly inside my back porch which is 43 feet long. I stapled the wire to the wooden beams at the top of one wall and mounted the box at the end closest to my coax feed through to the Florida room. I connected the ground wire to the aluminum frame of the windows at that end of the porch. Installation took less than 20 minutes from out of the box to on the air.

The surprise was the performance. It's certainly not a beam at 60 feet, but running five watts from a new IC-705 on both CW and SSB, in the last ten days I have worked stations as far away as 2000 miles including the US, Canada, Mexico, several islands in the Carribbean and Costa Rico. The SWR is below 3:1 on every amateur band from 80m to 10 meters except 20, 40 and 60m, and those three bands tune to below 1.5:1 quickly with my Elecraft T1 QRP autotuner. On 6m the SWR is about 3.3:1 but the 705 handles it without a tuner.

I'm glad I gave it a try -- its a keeper!
