421 Triband End Fed launched Jan 2017 which is G Whips 50th year, superb performance. During 12 hours of the  CQWW contest last October (noted as poor HF conditions due to Solar Activity see PW comments) we worked over 125 DXCC Countries with ease. At 12 Mtrs long it will fit in most back yards and is fabulous for Portable use. Comes with carry case as promotional offer, ptfe wire MIL spec wound Ni/Zn core or cores, kevlar lines, end support line and screw in insulator etc etc. available now. Models: 150w/250w/400w………….SO239 socket as standard, BNC/”N” Type special order.

 

150 watt pep version £75.00 (UK p/p £11)

400 watt pep superb unit £95.00 (UK p/p £11.00)

1000 watt pep £135.00.  (UK p/p £12) This unit uses 2 MEGA Ni/Zn cores and PTFE 7 MHz resonator.

G WHIP RESONANT END FED ANTENNA INFORMATION AND INSTALLATION

As of Jan 2016 these models are now tested at 600 watts pep.  UK recorded post & packing from £11.00

DSCN1466

Hang the box under the facia/soffit (items supplied to do this), pull out the un-noticeable green Kevlar line (unbreakable) at approx 45 deg angle down the garden, and off you go!………….why use noisy verticals???? why upset the neighbours???

Boxed with unbreakable 1/2 wave kevlar transmission line and support line plus cable strain relief and fittings, IP65 waterproof resin potted box fitted with low loss Teflon/PTFE UHF connector (SO239) for coax feeder. Facia board insulator included. Ready to go with no required adjustment as each unit is hand built and tested individually. “On the air in seconds”. Complete with spectrum sweep printout.

The G Whip End fed antenna is an end fed but with a difference! It incorporates approx 1/2 wave length wire radiator and also a G Whip resonant circuit and not the usual matching feeder line counterpoise used on many of the old designs or poor Iron Powder cores, a perfect tuned match. Nice and easy to turn to get the best signal or to cut the QRM. Each antenna comes complete with it’s own sweep and no adjustment is needed. Can be mounted vertically (not really recommended due to house wiring noise), horizontally or sloping, during tests we found sloping performed the best…….originally designed for the services for spot frequency operations, used by the ATC MOD and Australian Radio Network.

The antenna is end fed, meaning NO coax from the middle of the garden.

Buy it, try it, and you WILL come back for more of the other versions.
