POSTAL SITUATION: 1ST CLASS POST OR 24 HOUR TRACKED POST IS NOT GUARANTEED DELIVERY NEXT DAY (GO TO THE ROYAL MAIL SITE AND READ THEIR INFOMATION), IN FACT IT HAS TAKEN UP TO 7 DAYS FOR 1ST CLASS POST TO ARRIVE. IF YOU WANT GUARANTEED DELIVERY NEXT WORKING DAY IT IS ALSO NOT GOING TO HAPPEN AS IT TAKES 1 DAY TO BOOK A ROYAL MAIL COLLECTION AND YOU WILL HAVE TO PAY A PREMIUM PRICE FOR FOR A DELIVERY BEFORE 4PM. SO JUST BE PATIENT AS THERE IS NOTHING WE CAN DO UNLESS YOU WANT TO COLLECT THE ITEMS WHICH IS FINE. WE ARE USING 24 AND 48 HOUR TRACKED MAIL AND THAT WORKS FINE AND GETS THERE ON TIME, BETTER THAN 1ST CLASS POST!
We have had 20 units to test and pack today and most will be shipped Saturday 25th via Royal Mail, we have gone over our collection limit but they are offering to collect Saturday.
Over the weekend we will try to catch up on backorders and stock to be made, please persevere with us as things have been chaos in the past few days. More 2 and 3 core units will be ready early next week (the ones below). Thanks for your patience and mega business.
I moaned at him that the kevlar STINKS in the workshop (he says it does not smell) so we want to move it as we have too much, here is a deal you just cannot miss, a 49/1 200 watt pep resin potted unit, dual specially made cores (F14 Ni/Zn) unit with 22 mtrs of 45D commercial Kevlar and heavy duty insulator (giving you 7/14/21/28MHz). £25.00 plus £8.00 p/p (heavy box) (PTFE SO239 or “N” type or BNC)………LOL Nice I must say!

Next week we will start to clear some areas of the workshop loft, this will include large stocks of Disc Ceramic capacitors, boxes of them with several hundred in a box, also RF connectors mainly BNC 50 ohm single hole mounting as we only use 4 hole mounting and lots lots more. We will split up the items into bags so everybody gets a chance to grab something. COLLECTION BY APPOINTMENT ONLY. Pictures later.
FREE 49/1 UNITS: NO TUNER NEEDED:
We have a collection of new 49/1 units that were made for the ATC (MOD) and used for 5MHz but will work on 3 to 30MHz with half-wave length of wire for spot frequency, we are now confident that we have covered all orders and even sent out a few FREE spare units to the ATC, there are 11 units to clear FREE. These are rated at 50 watts pep and the connectors are: 5 x “N” type, 2 x SO239 and 3 BNC. Due to Royal Mail maximum collections of 5 per day and as we are VERY busy this in the first instance is collection only and 1 per person, if they are not cleared by mid October then we MAY post at cost. Units are pictured below. Later we will have about 25 to 30 various sample units 10/25/50/100 watt, these may have end user name labels on them so we may have to re-label them for security reasons.
45D KEVLAR ANTENNA WIRE
4.5mm (45D) dia heavy duty Kevlar ultra soft and flexible you can bend this commercial grade transmission line within 10mm, 250 kg breaking strain, 5kw++ pep power handling, heavy duty plaited copper braid with a lower resistance better than 28D or 32D versions, approx 500 kevlar strands, used for commercial HF arrays. Green in colour. We no longer stock 28D or 32D
There’s lots of variants of Kevlar wire around, some from Asia and the Eu but the best is British and always has been and always will be. 3 Companies in the UK manufacture various Kevlar wire sizes and have been doing so and supplying the MOD for over 50 years in the following dimensions: 20D (2mm), 28D (2.8mm) and 32D (3.2mm). We have documentation and reports of tests and requirements from Racal (now Cobham Antennas) MOD supplier Joyce Lobel and Plessey. The documentation includes the make up of the wire and it’s tensile strength etc. In the picture above on the left is the 2mm version, next is the 2.8mm version (which is a common version found in Ham Radio shops which G Whip Antennas (our old business introduced them to Kevlar), next is the 3.2mm and then there is a monster 4.5mm custom made special with over 500 fine kevlar strands which is much more than the 64 strands found in the 2.8mm version, the 4.5mm version has a breaking strain of over 250 kgs which is 3 times the 2.8mm version, just to show how big it really is next to it on the right is standard RG58 coax, put it up and it stays up for life. The resistive nature of the (45D) 4.5mm version is much lower due to the heavier weave of the plaited copper line. And on another note, several people report that some Kevlar wire is SILVER plated, this is untrue, Kevlar wire has never been SILVER plated, the braid is tinned so it can be soldered.
Approx 500 fine Kevlar strands inside the high platted plaited wire weave.
MOQ (Minimum Order Quantity 20 mtrs) and only available from us.
500 MTR DRUM £800 LAST ONE
Terminating/Dressing Kevlar Wire: Dressing Kevlar wire is very simple, when soldering you DO NOT chop out the Kevlar strands like some people suggest, you simply use a good hot 100-150 watt soldering iron and you end up with a perfect termination as below, buy it and we will even dress it for you FREE.

They ALL operate between 2 to 30MHz spot frequency with a halfwave length of wire or add 21 Mtrs for 7/14/21/28MHz or double the length for 3.5/7/14/21/28 and other WARC harmonics.
