Put one up the other day works well on every band except 40 swr is way to high on 40, all other bands are fine tuner will not tune it on 40. Any ideas?

The measurements on the HF10 on 40 are around 3:3:1 so outside the range of an internal tuner.

had problems with my new western HF10 about 5 years ago, phoned Fred the maker who knows the answers, problem sorted some great advice given.

Mine tunes up ok on 40m with my on board tuner in DX1200

i was given one on this forum for gb2 hcc and it works well with the ldg tuner on the 7300, since then i have made my own that i use at home and have a spare brand new one under the bench, cracking wee antenna that’s great for confined / restricted space stations,

the one at the castle was taken down for filming and i fear was taken by mistake buy the film crew as part of their gear, so i will most likely not put one back up,

i use rg213 on both the one at home and the one on the castle with no issues and think for what they are they are ok,i found the one at the castle worked best as it was at about 45 feet in a traight line rather than inverted V, the one at home is in an inverted v but rather steep angled but it works well enough or me to keep it up,

try a wheel ldg tuner if the antenna is outside the peramiters of the internal tuner,

Got it sorted everybody thanks for your help.

My hf10 will only tune between 7.130 and 7.160 swr is crazy on rest of band any ideas?

rg 213 ?

how high is the feed point from ground


bob.

Yeah RG 213 feedpoint is 30ft above ground.

I don't use a ugly balloon but have you tried one,

my feed point is just 10 feet straight feed with rg 213 and 30 foot back to the radio ?

thanks

bob.
