My RM14 HF dipole antenna can work pretty well but for serious monitoring as you guys called it, I have yet to know of any cheap directional antenna out there. Homebrew or commercially available. HF sets can be cheap but how about antenna?
The cheapest homebrew Tribander Yagi I know and built up cost me no less than 1k and cheapest entry level commercially available is 3.7k. AND you need minimum turning radius of 30ft on roof top. Most terrace houses in Malaysia is about 24ft wide and unless you have a very very nice neighbour or a detached house. I have not include the rotator. Cheapest rotator out there that can turn a 20kg antenna RM550.
People tend to shy away from HF due to this costing but when they got bitten then they will venture there automatically. No need to belittle VHF/UHF people here. I recommended a re-budget and not kicking them in the balls for staying within 2M.
Don’t worry about the antenna…If you are so serious about it no need for you to spend
3.7K for the yagi. I spend less than that…..I am very lucky even though my terrace house is about 24 feet wide I can still put up my 4 element Yagi the longest element is 26 feet.
If you are interested with the tri band yagi it cost you less than RM700 I have tested this tri band Yagi two month ago……at one of the Dxpedition. Talking about rotator u can modified some motors or use servo motor some of the old timers does’t used rotator they use “Armstrong Method”……..there are so many things u can do don’t limit ourself.
During 1991…92…93 when propagation is good I used to work Europe and US using my
Simple dipole because that time I cannot afford to have a Yagi and Rotator…….You can build your own Delta Loop Antenna by using electrical wires and for info this antenna performs better than the Yagi ……and its very cheap less than RM150.
I don’t belittle VHF/UHF people here but what I am trying to say here do explore some other frequency which is more interesting and learn more things there………I am trying to share some of my experienced and knowledge, even some of the 9Ws which I met said they are getting board listening and talking on VHF…..….we cannot stop people from doing what they like……If you are happy and satisfied what you are today than we cannot stop you….just enjoy yourself….and be happy with it.
