<p>I believe that all Wharram designs have raked masts of about 7 - 12 degrees in the different designs.</p>
<p>I wonder whether those who installed antennas in the mast top compensated for their mast rake, and whether there is any experience whether the installation in a strictly vertical position (deviating back from the mast rake) increased performance in either VHF or AIS.</p>
<p>From theory it seems obvious it should increase performance, even more if someone using higher gain antennas…</p>

<p>From theory it seems obvious it should increase performance, even more if someone using higher gain antennas (e.g. 4.5 or 6 dbi as opposed to 3 dbi.</p>
<p>The two Wharrams I bought in the last 10 years both had the antennas following the mast rake, i.e. not strictly vertical. Whilst the first boat had only VHF, I did never try to estimate how performant this was. The second boat had VHF/AIS combined with a splitter, The AIS VSWR was always to high (3:1), so probably transmitting was not very effective.</p>
<p>I wonder whether this was (partly) caused by the antenna position?</p>
<p>Any experience or ideas around?</p> Untitledtag:wharrambuilders.ning.com,2022-05-26:2195841:Topic:2933352022-05-26T14:17:31.620ZRob Daiglehttp://wharrambuilders.ning.com/profile/RobDaigle

<p>Hello folks<br/>What kind of VHF antenna do you use in a Tiki 38. Top of the mast is the best place to install it.<br/>And the SSB antenna?<br/>Thanks a lot</p>

<p>Hello guys<br/>Here in Brazil is mandatory to have an SSB radio on board.<br/>So do you guys have some tips about brass grounded plate? Size and local to fix it, with hulls in the hull or another way?<br/>Thanks very much.</p>

Hello everybody<br />
I have just installed anew nav tri light & anchor light with a three position switch. 1nav 2 off 3anchor. The switch works properly but the lights are dim the bulbs are LED 4W which seems ok to me. Does anyone have any idea what could be wrong? Cheers Ray

<p>Bonjour,</p>
<p>I plan to put a battery and have it maintained with a solar panel.</p>
<p>I understand that + goes to + an - goes to -, but am I correct with that design? In fact, is it possible to plug the enegy wires charging the battery via the solar panel together with the "output" wires going to the electric panel for repartition?</p>
<p>Thank you for your answers,</p>
