[Elecraft] PAR/LNR EFHW antenna

[Rich Arland]

I have one of the original PAR end fed half wave antennas prior to LNR taking over production and sales.


Everything is present EXCEPT the little matching network that couples the EFHW to the radio. I tried contacting LNR to obtain a new one but they told me that they couldn't do that, BUT they would sell me a new version  of the complete antenna for the paltry sum of around $80! I said "no thanks" and hung up the phone.


I am after the schematic or the best guess of the components and parts placement that will resonate this 40-30-20M antenna. It's not rocket science but it's close!! As I understand it these antennas are fairly high impedance wise, so I need some kind of matching network to bring that down to around 50 ohms for the KX2.


Failing that path, has anyone hooked an EFHW to the internal ATU with good results? I would also include a cut to frequency ground radial that I would lay out below the antenna. That would be the easiest thing and simple to employ.


Over the next 10-12 days I am planning on doing some portable operating from MD and PA. Taking the KX2 with me and hope to get some operating time between family obligations.


Opinions, observations, ideas please.


Vy 73 es gud DX!
