Product Description

½ Wave, 6-Band HF Cobweb Antenna 300 watt

Restricted space spoiling your operating fun? 
MFJ-1836 puts your call back on the map! This fsix-band (20, 17, 15, 12, 10, 6 Meters) half-wave open-loop is perfect for restricted space or portable operation. Sky-gray fiberglass spreaders and nearly invisible wire elements (12’ diagonal), blend in with your surroundings while standing tough against nasty weather. 

It is horizontally polarized for less local noise pickup plus has solid gain over verticals. No radials needed! Low SWR is due to MFJ’s exclusive Spider-MatchTM broadband network. Up to 5 dBi gain will allow you to work DX easily -- even on QRP. The radiation pattern is nearly omni-directional so you don’t need a rotator. Use lightweight TV hardware to mount it on your chimney, balcony, fence post or other. Has SO-239 feed point. It’s small in size, just 8 lbs., low in cost, but big on performance. Let the MFJ-1835 turn your space problem into a fresh stack of QSL cards from far away places.

The MFJ-1836 is a compact six-band loop array especially designed for limited-space installations. Using horizontal polarization, it packs a 3-4 dB gain advantage over ground-independent verticals plus it boasts superior immunity to local noise and RFI. 
In addition, MFJ’s highly efficient Spider-Match® network and adjustable tuning tabs guarantee low minimum-SWR on every band. 

MFJ-1836 only measures 9-feet on a side, yet it features a full half-wave element on every band for no-compromise DX performance -- even when running QRP! 
The MFJ-1836 is solidly constructed to take on extreme weather. With sky-gray fiberglass spreaders and stranded-wire elements, it blends in with any backdrop. 
Best of all, it is omni-directional, so you can omit the rotor and mount it high in the air using standard low-cost TV-antenna hardware. 

Five concentrically arranged 1/2-wave horizontal loops are mounted on a fiberglass X-frame. The footprint is square, with all six elements fed in parallel through a reactance-compensated broadband autotransformer. The radiation pattern is virtually omni-directional (± 1.5 dB). A sleeve-style ferrite balun is installed at the feed pont to choke off unwanted common-mode radiation. The balun also reduces receiver-noise pickup and spurious RFI signals generated by consumer devices. Weighing just over eight pounds, the MFJ-1835 installs easily on virtually any portable or permanent mast from 1-1/4” to 1-3/4” OD.
