Thanks mike. Yes I know the lower loss cable should go to the higher loss freq antenna but, it wouldn't reach. LOL This whole conglomeration is completely temporary for experimental purposes and because I can't shell out the $ for the mast I want at the moment. I think I'm gonna have to go to...

Made contact on 2 meters as soon as I flipped the antennas. Things are looking up. Kinda. Now my swr is way up on both antennas! Darn it. I had them tuned well before. I'm assuming it is the metal mast they are bolted to. it is not grounded but probably acting as a giant reflector element? This...

Flipped em both. Made a contact immediately on the local repeater. RX went from s2-3 to s8-9. Bad thing is... now my swr is way up on both antennas! I had them down below 1.5:1 in the middle of the bands. Now Im lucky to be below 2:1. I can't believe this! :angry:

Thanks Got it! Double!

Ha! Thank you very much! I'm dragging both of those down today and flipping em. Yes I am sending the tones to open up the repeaters (I'm pretty sure). I look them up on the internet or My radio searches for the tone for me and let's me know when it hits. You've been a big help. I am joining the...

Ok thanks CK. Yes the 2 meter yagi has a gamma match. The 70 cm is as You say direct fed. I can't seem to reach anyone via the repeaters I'm picking up. Of course my radio is only showing at most s3 when I in on the signals with the rotator. I also might not be programming my radio correctly. I...

Ok a couple questions. I'm a total rookie and tend to leap before I look or (in this case read). I built both of these yagi's. 70 cm and 2 meters. My reasoning for building 2 instead of a single dual band was good band coverage for each. My MFJ bridge confirms the 2 meter one has nice flat swr...

Hey all, My single wire antenna is hung from my mast fairly close (within 1 foot)to the metal guy wires (they are isolated from ground) and is in an inverted V config. My SWR at 10 meters is flat but I'm wondering if there's any parasitic losses happening. Also, do the support lines on the...

I passed my tech test the other day but I've been working on my rig and such so I'm ready when I get a call sign. I got the designs for all off of the good ole internet (it has to be true right? LOL). Had to do some serious tweaking to the 2 meter to get it to resonate where I wanted. The 70 cm...

Thanks Cpt. I agree with not having both on same "tenna" after some research. I built a 70 cm yag from scratch "mostly". I'm positive the coax will weigh at least 10 times the antenna since I plan on using LMR400 or RG8U because of high losses at vhf. Can't wait to try them out. Just passed my...

Well I built a 5 element yagi today for 70 cm. Used an online calculator for lengths , spacing etc. I was shooting for 435mhz. Well according to my rig, the sweet spot is about 436mhz. That's ok BUT, at 430on down and 440 on up swr shoots through the roof and my rig (ft857d) starts flashing me...

Hi all. I built a 4 ele 2 m yagi from an old tv antenna. Is there a way to add 70cm 's to it and utilize the same feed point (I can move it obviously)? I've seen dual banders but they had separate feeds. I really don't want 40 lbs of LMR 400 on the same mast. (JK LOL) 73

Thanks Jeff and 73!

I happened upon an old Philmore FSM55 meter from the 80's?? Have the unit and box but no manual. Searched online but cannot locate a PDF or anything referring to the manual. Wondering if anyone on here knows about it or location of the documents I'm looking for. The power meter reads exactly...
