i want to put on the air the klm 40m-2 antenna that i get like 7years ago, i
never use it , i get from a friend in los angeles to another friend here in
Mexico but at the end i finish with the antena, i start to clean/ensambly the
antenna, looks for missing parts , but not, all looks fine except for a few
clamps that need to remplace , this one come with the balun upgrade , a big
with balun , his mounting plate and the double teflon cable rg-142 with one pl
259 at each end.
i start gain but a 12 dbs f/b swr 125 khz 1.5:1
i get the info from Msquare and they have a model with a 4.2 dBd in a 19' 7"
boom same bandwith
i have my hy-gain discoverer 72 that claim in the manual 4.3 dBd , 15 dBd
F/B also claim a swr bandwith + - similar (they use the 2:1 reference
187khz) but in my antenna show a 210 khz 1.5:1 bandwith at 140ft high.
this is for the question, i will get more gain and f/b if i use the same
separation that Msquare or Hy-gain ?
or was the best or optimal separation for this class of antenna with linear
i have more pipe to extend to that size. i will like to get the most for the
tnx in advance
