Hi Keith if you want a quick deploy HF aerial then buy a 100ft steel role reel up tape measure. Make great aerial and has measurements. Works well with a 49:1 . Cheers from old George in the UK.
I purchased and built the ARRL 40 meter End Fed Antenna. It has the same radiation pattern as my DiPole but it has a bit more noise on receive, probably due to the much higher feed point impedance. Using it with my Elecraft K3 and the 10:1 internal tuner It will tune up on 80 - 10 without any problem and sometimes I can get a 1.2 :1 on 160 and 6 meters. In general I am very happy with the EFHW antenna. The voltage and current distribution across the antenna is exactly the same as the center fed DiPole. No counterpoise is needed.
Are you saying the wire I have clamped on the shield is not needed? I've read both, from what I understand the EFHW uses the coax shield, but you need a longer (25-30 feet) coax than I have here so I added the piece of wire shown in the video for that reason, I also read placing it directly under the antenna would help with NVIS. I am happy to be corrected, let me know if I did something wrong here. so far I am favoring the EFHW over the center fed dipole in every scenario, but I still want to play with it more. Even if the center fed is better by say 10 percent, the End fed is so much easier to deploy.
You might move the radial 90 degrees to the antenna wire. I use a 50 foot piece of rg-213 without a ground radial. I make contacts into the UE, Japan, etc.
@@tshirley05015 so far, that's the plan. The EFHW is much easier to deploy. I'm using the camper to test as many antenna setups as I can as it is easier to mount stuff to and test. I agree, the end fed seemed to work just as well as the center fed with smaller wire and It has better swr on multiple bands compared to the center fed.
Yea I know this isn't really scientific at all. I'm still trying to figure out how all this stuff works, but I was really pleased with what I saw in the EFHW vs the center fed dipole.
I am glad it made sense to you.

@@tlnelson7598 I'll give that a shot. I am focusing on nvis for statewide coms right now, but will be looking at dx soon.
I couldn't tell enough difference between the two antennas, I would go with the easiest one to deploy.

Keep in mind the dipole is running the opposite orientation than the 49:1 to it isn't really a fair comparison.
