# Will using a loaded coil antennas have detrimental effects on QRP operations?

I was looking for a 40 m antenna for QRP CW operation at 3 W. I looked at the Wolf river coil which is a nice portable antenna. From speaking with other hams they mentioned loaded coils are poor for QRP operations and told me to DIY a quarter wave antenna I've already spent like \$140 on the parts for my DIY antenna including a$100 telescopic pole and I am considering if I should just return all these and get a prebuilt loaded coil antenna instead.

Am I making the right choice opting for a DIY antenna over a prebuilt loaded coil?
