WORKSHOP CLEARANCE

RE-OPEN FOR SALES 1ST JUNE 2022

We have a mega amount of items to clear including: complete 49/1 units single and bulk buys, pre-wound baluns, un/un units, pre wound cores, TRUE 4/1 Current baluns with multi-cores not the fake single core things, radios, antenna analysers, test equipment, antennas, kevlar wire, PTFE tubing etc. Many of our commercial units have certification for commercial use. The quality is superb which is reflected in the sales and feedback of both G Whip Antennas and RFCOMMS over many many years of commercial designs. All our baluns and matching units are resin potted for stability and long life and made from top grade quality components. Take a look below!

For a multi-band antenna FORGET any 4/1 or 9/1 iron powder made matching units, they are lossy and useless compared to a Professional made Ni/Zn unit. The-End-Fed-Half-Wave-Antenna (CLICK THE LINK AND LEARN)

Also look and read the RESONANT antenna ideas on the QRP page (CLICK THE LINK), lots of low cost proven ideas/designs used by overseas Commercial users of top grade commercial radios (MIL SPEC NSN). There’s no YOU-TUBE videos just good old sound knowledge of many years of commercial communications around the World and inventive ideas for covert comms for the Professionals.

Original designers of the “G Whip” single band resonant and then the multi-band antennas using the 49/1 un/un many yeas ago, READ THE LINK. The-End-Fed-Half-Wave-Antenna

G Whip was passed over to a new owner in 2016/17 and we then concentrated on Overseas end users of Commercial HF Transceivers. 2021 saw us retire and now we are clearing stock items at crazy prices.

Same as above 49/1 unit but 200 watt dual core (Special Ni/Zn/F14 grade much larger than FT140-43) commercial version for portable applications. Just £25. 

Same as above 49/1 unit but single special core 100 watt pep version. Resin potted, PTFE SO239, SS fittings, Just £20: 

Sweep below shows 7/14/21/28MHz with 21 mtrs of wire or you can use a halfwave length of wire for spot single frequencies 2 to 30MHz, pure resonance and no lossy tuner needed!

4/1 CURRENT BALUNS:

True 4/1 current baluns 50 > 200 ohms, the correct unit for Delta loops, Windoms and Doublet antennas, PTFE wire in PTFE sleeve wound on custom made cores much larger than FT140 types, PTFE SO239 socket, stainless steel strain reliefs for line, coax and heavy duty M6 unit for mounting, resin potted, simply the best. LF RL = 32db > 25db @ 50MHz. Provides common mode choking. £30.00 

  Super sweep, super construction, good up to 50MHz with losses, commercial quality.

The REAL current balun! 2.7MHz = 1.05 VSWR = RL of 32db, @ 30MHz VSWR = 1.19  = RL of 22db, you do the sums!

4/1 UN/UN UNITS

4/1 Un/Un units, useful to play with (ie RYBACOV antennas) but offer no resonance and will require a matching/tuner unit, 100 to 500 watt rated, resin potted, PTFE SO239, stainless hardware, several types available, great quality and prices as using up the new old stock. From £25.00
