Mike,

I forgot to tell you, I purchased a 706M2G from Robert at HRO for $100 last 
month. He had said to mention that to you since you had been looking for such!

Go for it. List away.

If it’s a Icom 706 Mk2G for $50, I’ll take it!

I found a MFJ model - MFJ-1982HP is rated for 800pep
https://mfjenterprises.com/products/mfj-1982hp

This antenna is available in three power ratings:
MFJ-1982LP – 30w
MFJ-1982MP – 300w
MFJ-1982HP – 800w

Anyone have experience with this antenna?



A couple of questions –

  1.  If you have experience with high power (>= 600w) transformers for EFHW 
antennas, what design did you use
 *   Core type and number of cores
*type 53 has a higher curie temp as opposed to type 43
 *   Wire AWG?
 *   I see a number of YouTube videos recommending 56:1 as 49:1
*   Comments?


  1.  What is your recommended wire for the radiation element?
 *   Material –

i. Copper over steel?

   ii. Hard-drawn copper?

  iii. Other

b.AWG?

i. Number of Strands & 
strand count?

c. Jacket material

d. Other?

Your guidance is appreciated!

Subject: Re: [BVARC] Is it ok to list equipment

Hi all,

Here is what is taking up desk space: Ameritron AL-80B.
I moved from Liberty county a few years back into an HOA.  I just don't have 
the antenna's to warrant that kind of power here.  It has had very little 
actual use.  I've been turning it on occasionally to power up the caps, etc. 
and to check high voltage.
Tested last week and it seems to be working as it should.

Bought new: always non-smoking home.

I am asking $1800.00 (pick up in the Humble area) and will include the MFJ - 
998 "IntelliTuner" for that price.  I have the box and manuals.

If interested:

BTW, for antenna wire, see articles by our own Rick Hiller in the technical section at
www.bvarc.org . I think he's addressed this subject.  I like #14 or #12 insulated.  Solid or stranded choice depends on your strength and flexibility requirements. Thicker wire gives a slightly better bandwidth
 at the cost of weight.

See product design specs, as well as articles, at Balun Designs.Com. use the core mix type for the bands you'll operate on.  For high power, double-up on size 240 cores.  Youtube "TRX Bench" channel has a great 4-part video series on building
 baluns.


My experience tells me that if I want a long lasting, reliable balun (good quality components and workmanship that withstand the elements), it's more cost effective to buy off the shelf from Balun Designs or equivalent. (The amount I saved wasn't
 worth the trouble.)  Of course, making my own is fun and educational; but I now buy my baluns from Bob.

I am interested in EFHW antennas for primary use on 20/40/80m – but want to be able to run my Worthmore 600w amplifier.
I found a MFJ model - MFJ-1982HP is rated for 800pep
https://mfjenterprises.com/products/mfj-1982hp
 
This antenna is available in three power ratings:
MFJ-1982LP – 30w
MFJ-1982MP – 300w
MFJ-1982HP – 800w


Anyone have experience with this antenna?




 
A couple of questions – 

If you have experience with high power (>= 600w) transformers for EFHW antennas, what design did you use
Core type and number of cores 
 type 53 has a higher curie temp as opposed to type 43
Wire AWG?I see a number of YouTube videos recommending 56:1 as 49:1
Comments?





What is your recommended wire for the radiation element?
Material –

   
i.
Copper over steel?
  
ii.
Hard-drawn copper?
 
iii.
Other


b.AWG?


   
i.
Number of Strands & strand count?


c. Jacket material
d. Other?


 
Your guidance is appreciated!
