POWABEAM ANTENNAS - G6HKS YAGI KITS AND PARTS

Visitors Online:  Total Today: 

Hello from Richard G6HKS

... Some of you may know me, I am a keen all mode VHF and upwards DXer but like many have a less than perfect radio location – this has obliged me to optimise my station to the best of my ability – to this end I became a fan of Dereks PowAbeam designs which never cease to amaze me – My goal is simply to make it as easy as possible for Radio Amateurs to construct their PowAbeam – whether it be for a local rag chew or some serious DX'ing.

After a few gentle prods I will be spending some more time to keep this site up to date and add some interesting features. To start with check out the LDMOS PA menu selection which is a photo file of my 432 500w pa project, i hope it inspires you to do similar. If all goes well i will rapidly move onto the big brother twin offering 1000w . Power provided courtesy of a converted ex HP Network power supply (60 amps at 50V for £50 !!!). Key skills to successfully make a working amplifier are reading instructions carefully , practice soldering SMD devices with appropriate static protection and some reasonable metalworking , tapping threads type skills. Parts wise you have RFHAM and W6PQL. Personally Jim W6PQLs website and kits are outstanding – i was originally drawn to Jims site needing an effective sequencer to – his kit is great and maybe a good starter kit for those new to SMD construction. Jim also has many useful video clips to help you along. I opted to get the heatsink from RFHAM (on its own a work of art) and all other stuff from Jim (control boards, RF, Filter) . Ancilliary stuff from Ebay, RS components. I will post more as the project progresses – watch this space

This weekend (27-28 July 2013) saw me playing EME and testing out MAP65 – excellent ‘moon’ and what a truly awesome piece of software MAP65 is – i have some recordings that i will be posting to You tube in due course of the weekends fun. I did a bit of transmitting (12 QSO’s new one for me was HL5QO South Korea –20 both ways many thanks Jinson) but it was great fun just to view MAP65 in action monitoring multiple qso’s – for my mini 17dBd array 20+ qso’s at peaks. Biggest signal winner went to I2FAK with a booming –10 JT65B typical signals in the –18 to –20 area. I now use a HA8ET 0.4 dB nf at the masthead on receive- MAP65 driven from a funcube dongle proplus via a feed inside my FT847 - running standard WSJT for tx/rx. I can use the FCDP+ even when the rig is switched off and gain a 1.5db benefit by doing so - eventually I want to put the funcube at the antenna masthead and then run wireless/cable to the shack for nil feeder loss + rig switching loss = 2dB (serious benefit for EME) – all in good time

I am aware that we have a lot of designs here and i will be reviewing the range in the near future to make it clearer how to choose the best antenna for YOU – Derek G4CQM also has some great new designs which can be seen at his site and I will be bringing the best of them here (VE7BQH listings also offer independant assessments) – remember our kits are material so you can make any design you wish – per elements / boomlength of your choice . Any bespoke orders , parts etc let me know and i will be happy to price up for you. interested in becoming a paraclip distributer in AMS or APJ region drop me a line

So whats the PowAbeam USP? – we have four of them ...

For EME I use Dereks 4 x 2M7N50 (original design) which frankly provide more performance per metre than any other design (at the sacrifice of narrow bandwidth and some wet weather sensitivity) – for example the 7 ele N50 provides 11.2 dBD on a 3 metre boom !!!

Check the BUILD page for notes and tips on construction , on the PRICES page we offer various material kits so you can homebrew you own PowAbeam at low cost. I am also very happy to cost up any bespoke order just let me know what you are after.

Making a PowAbeam is straighforward (no tuning - no baluns – just make it and go) you need some basic construction skills and should view this as a learning project with a high performance yagi as the end result – you will also see a number of articles / construction notes on the PowAbeam site to help you.

Optional service I am happy to make up the driven element and accurately cut / drill parts for plug and play just ask for this service and allow two weeks please.

Finally its good to know that our designs are being adopted by so many of you and behind many long DX QSO’s there is often a PowAbeam at work

I look forward to hearing from you...
